What is KnujOn?
KnujOn is a completely new approach to the ever-growing junk email problem. KnujOn is a multi-tiered response to Internet threats.

I already have a spam filter/blocker, why do I need KnujOn?
Filters and blockers stop spam from reaching mailboxes but do not actually stop the flow of spam. The messages pile up and must be reviewed and deleted.

How is KnujOn different from current anti-spam programs?
Filters and blockers search emails for keywords and other content that flag messages as possible junk mail and then divert the email to a quarantine area for review or deletion. KnujOn takes the junk email and uses it to track and stop the sources of the junk.

What does KnujOn do?
KnujOn is a policy enforcement engine. KnujOn has a powerful records interface that can also be used a forensic tool. KnujOn sorts through thousands of emails and profiles vast e-fraud operations so they can be shared with law enforcement and financial instutions.

Does KnujOn practice hacking or use denial of service attacks?
No. KnujOn is a policy enforcement, reporting and tracking tool.

Does KnujOn spam the spammers?
Absolutely not. We contact junk mailers in proportion to what they send out to our clients. Internet criminals will often accuse us of spamming them because we sent one or two opt-out messages on behalf of a client. It is a garbage tactic for them to play the victim.

How is junk mail different from legitimate marketing through email?
Junk mail companies use spoofing to conceal their identity. Legitimate marketing companies typically follow accepted privacy practices and honor removal requests.

What is spoofing?
Spoofing is a technique of forging an email address to hide where it truly came from. Email headers may be modified to insert bogus "From" information.

What is a forensic tool?
A forensic tool is something that gathers and sorts data so it can be used in investigations or as evidence.

How much is a KnujOn membership?
$27 per year for individual members. However, there will always be a free component.

Is it intended to replace my spam filter/blocker?
KnujOn is designed to work with your current email protection or alone.

Can I use KnujOn for my personal email?
Yes, KnujOn.com personal service is available: More information.

Could KnujOn be improperly used against legitimate sites?
KnujOn processes junk mail and reports sites that do not comply with rules and regulations. Legitimate sites are not affected. In addition, .gov, .mil, and .edu sites are exempt. KnujOn will not run policy enforcement against charities or polictical organizations.

How do junk mailers get email addresses?
There are several methods. One is simply buying lists of emails from on-line companies. If you have purchased something on-lie, you may get junk mail. Junk mailers also have programs that scan the Internet for email address posted on web pages. Because of this certain people have warned against posting emails on web pages but I think this voids a vital purpose of the Internet, namely communication. Everyone should be able to post their email somewhere without worrying about junk mail, and to help we designed KnujOn! A third common method to send junk mail to range of possible addresses until a match is found. For example: aaa@hotmail.com, aab@hotmail, aac@hotmail... You may have received junk mail with various spellings of your name in the distribution list. One of the worst ways to harvest addresses is through viruses. Some viruses(trojans, spyware) infect email software and steal your contacts list. But with KnujOn, these individuals can be found and shut down.

Why does "unsubscribe" not work?
There are many legitimate companies who adhere to requests to unsubscribe. Spammers don't care, they ignore unsubscribe requests.

What about laws that make spam illegal?
Making junk mail illegal may sound like a good idea, but it will not solve the problem. Many Junk Mailers are in foreign countries and cannot be touched by U.S. laws. Spammers also conceal their identities making it very difficult track where the email is coming from. Since the CAN-SPAM Act has gone into effect the junk mail levels have trippled.

What about recent arrests and lawsuits?
These government actions are the result of extensive investigations taking months of man-hours and unknown amounts of taxpayer dollars. Their efforts should be lauded, but this is just the tip of the iceberg. To expend these resources for every junk mailer would be an extremely expensive venture. This tactic would be ineffective against junk mailers in other countries.

What about improvements in content filtering?
The developers of content filtering software have come up with some truly amazing innovations. Unfortunately, the junk mailers are constantly finding ways to bypass the filtering. What if you work in a pharmacy and you have a legitimate reason to send email with "Viagra" in the content? Recently, a version of the sober virus sent millions of junk emails in German. None of these emails contained English words that were on block lists, but they had violent sexual language in German. The emails bypassed blocking.

How much of a problem is junk mail?
Recent studies show that 90% of all email traffic is junk spam. AOL reports that their users receive 10 million junk messages every day. Some studies estimate that U.S. employees lose 3.1% of their day dealing with junk mail, that is about one and a quarter hours per week, over 300 hours per year.

What are the problems with current strategies?

  • Use a filter or blocker program
    Most networks use some kind of spam blocker or filter. These programs effectively keep junk mail from reaching mailboxes but they also block some legitimate mail and allow bad messages to get through. Blocking and filtering do not stop the problem, only delay it. Why Content Blocking Does Not Work.

  • Don't post your email address on web pages
    While spammers do use programs that harvest emails from web pages they also obtain lists from other spammers and send junk to random emails until they get a hit. This strategy also violates the point of the Internet, communication. Why should we hide from them?

  • Use temporary email addresses and dump them when spam shows up
    Sounds like they have you on the run.

  • Never buy anything from a company that spams
    I totally agree. However, they will still make money from a minority of people and keep spamming everyone. Also, believe it or not legitimate on-line companies sell your address to spammers.

  • Hack the spammers
    Lots of work and now you are breaking the law too.

  • Sue the spammers
    Expensive. Time-consuming. Limited results.

  • Pass laws that make spamming illegal
    Speeding is illegal, people still do it. Try enforcing these laws in foreign countries.

  • Code verification
    Many email services will display a random set of non-ascii(images) letters and numbers for a user to enter in order to verify that a real person is sending email and not a script hacking a mail account. This is clever concept but it wont stop them.

  • SMTP relay limits
    Many mail hosts will limit the amount of mail that can be sent to 500 or 250 emails per day per email address. However, if a spammer has 10 sites with 100 email accounts on each they can send half a million emails per day.

Yes, send it to: nonregistered@coldrain.net, OR use one of the specific addresses listed here: Instructions for sending email, OR become a member.

Do you need full headers?

There is also an open Knujon forum on CastleCops

What is difference between yourjunk@knujon.com, knujon_us@yahoo.com and other addresses?
knujon_us@yahoo.com was the original reporting and contact email address for this project when it was in its beginning stages. When Knujon.com was launched, the reporting address became yourjunk@knujon.com and the contact address became contact@knujon.com. Because of issues with our IP many users experienced problems forwarding junk mail to yourjunk@knujon.com so we offered knujon_us@yahoo.com as a temporary alternative while we found a permanent solution. Registered users are now issued a rejection-free address to report junk to. yourjunk@knujon.com is still valid and junk sent there will be processed. We would prefer that knujon_us@yahoo.com no longer be used. Email forwarded to knujon_us@yahoo.com will still be processed but it takes more time. We understand that many users have automated the reporting and that a complete switch-over will take time.

Do you only take some kinds of junk mail?
No, we take it all. Spam, phishing, stock junk, "awards", "degrees", Rx, unsolicited pornography, mortgage offers, software offers, whatever. Instructions for sending email.

Are you out to get all email marketing?
No, only unwanted and fraudulent email. We believe that the marketing industry has been unfairly tainted by online scams.

If I am already reporting to another anti-spam service, should I stop and only send to Knujon?
No, we want the effort maximized. Report to anyone who will listen.

What steps do you take to protect innocent parties?
We are well aware of the extent cyber criminals will go trick, defraud and embarrass lawful organizations and companies and Knujon.com makes every effort to protect the innocent. Even Knujon.com has been a victim of spoofing. The first thing to be aware of is that all .EDU, .GOV, and .MIL sites are exempt from this process. Secondly, we have an enormous list of trusted sites that include legitimate companies, news services, non-profit organizations, banks, and other entities. Email reported to Knujon with any information relating to these sites is treated as a phishing or smear attack and we cooperate with innocent parties to report and stop the potential fraud. We encourage all site admins who have been victimized by phishing to register with out Alert System.

Are you out to stop on-line pornography?
No, with two exceptions: porn pushed through junk email and evidence of child sexual exploitation. We will do everything in our power to report crimes against children and cooperate with authorities to ensure that the perpetrators are prosecuted to the fullest extent of the law.

Are you out to stop on-line gambling?
Not specifically. Lotteries, racetracks and casinos exist all over the world. Some believe it is personal choice others a menace. The online gambling issue is a complex and controversial subject that KnujOn does not intend to address at this time. However, we will address unwanted gambling-related emails.

What is a "multi-tiered" approach?
Rather than relying on a single method KnujOn has developed a toolbox of procedures that address junk email on many levels.

Does KnujOn use blackholes or blacklists?
KnujOn does not use or maintain blacklists or blackholes.

Is there software to download or maintain?
No. There are extensions and add-ons for email software that make it easier to report to KnujOn but there is no "KnujOn" software to install.
