PUBLIC MARKS from svartling with tag spam

Once you have a blog that gets any amount of traffic, you will eventually get bombarded by TrackBack spammers (people who send a fake trackback ping to your blog to try to increase links in to their site when their website doesn't even mention your post, your blog, or anything to do with the subject).

It seems like google has purged many scraper sites from the google serps, as per this thread: http://www.webmasterworld.com/forum30/30530-2-10.htm I'm sure many people, including myself are very, very pleased about this as it stops scumbag sites from stealing our content. However, it also appears that some non-scraper sites have been included in this purge (including my own). My site has been active for 5 years and is based on unique content. Has anyone else been effected by this, and does google intend to refine the algorithm to stop valid, unique content sites from falling victim?

Spam is one of those things that nobody wants, but probably has plenty of. If there happens to be anyone out there unfamiliar with spam, we are not talking about the luncheon meat, but the unsolicited, junk e-mail that clogs our inboxes.

Bad Behavior is a set of PHP scripts which prevents spambots from accessing your site by analyzing their actual HTTP requests and comparing them to profiles from known spambots. It goes far beyond User-Agent and Referer, however. Bad Behavior is available for several PHP-based software packages, and also can be integrated in seconds into any PHP script.
