As posted on JAGK.com, a domain preemptively stolen from a referrer spammer and named “Junk and Gunk Knowledge.” The domain has since then been sold and become just another spammy placeholder.
Link Spammers are Evil And Twisted and Will Gladly Screw Up Your Site Just For Money
Link spammers roam the internet, posting unsolicited advertising for pornography, gambling, and drugs to weblog comments; machine-gunning trackback URLs with multiple pings; filling up your referrer logs with bogus links; and using up your website resources in the process, flooding your logs, consuming your bandwidth, even taking your site down. They are doing everything they can to fool search engines into thinking that you are linking to their junk, thus polluting your site — and the rest of the web.

Spammers are using fake “suspended” pages
Spammers are registering domains and pointing them to fake “account suspended” pages to make targets think that the spammer has already been caught. In truth, their accounts are still active, and the suspension pages are later converted to sleazy affiliate and link farms.

Protect yourself from link spammers
Hide your referral logs. Make sure your stats and “recent visitors” scripts are password protected and/or hidden from search engines by a robots.txt file. Don’t show “recent referrers” on your weblog, but if you must, use the
Protect your weblog comments. Install comment-filtering if your weblog software doesn’t already have it. Use comment moderation and user authentication. Apply captchas and Turing tests to make sure that humans are posting and not spambots. Block accesses from known open proxies, zombie machines, and spambot user-agents.
Protect or delete your weblog trackback functionality. Trackback is harder to protect from spammers since it is a more automated process. Look for filtering/moderation solutions applicable to comments and trackback simultaneously. If these don’t work, you may have to deactivate trackback altogether.
Upgrade your weblog software. If you are running Movable Type, WordPress, or other weblog software on your own server or web hosting account, upgrade to the latest version and note all security bulletins provided by both the software developer and your own webhost. Any functionality which allows people to freely generate content or send email is at risk.
Your poorly maintained weblog may be a RED HOT SPAM MAGNET!
Did you jump on the blog bandwagon earlier on, only to forget about it a few weeks later? Or do you have comment notification turned off, and not care about what goes on in older entries? If your site is still up and running on old weblog software, the comment and trackback scripts are most likely attracting spam, using up your site’s space and bandwidth, and polluting the rest of the web. You’re part of the problem! Try searching your site for common spam strings. If you find spam in your comments or trackback sections, delete it, and follow the steps above to protect your weblog from further invasion.
These guidelines also apply for your referrer logs. If you’re running public referrer logs, hide them behind a password, put a robots.txt in the referrer directory, and slap
rel="nofollow" onto all links.
If you’re not up to the task of keeping up with all this spam-related info, go with a centralized service like Blogger or Typepad or someone who’ll take care of spam filtering on the server side. Today’s web needs responsible and vigilant weblog owners!
