It won't stop those pain in the arse spammers trying referal spam on my site (I don't even publically show referals, so it's useless for them anyway) but I've just cleared out my referal logs. Removing v[insert word here].com, any domains containing "real-estate" (or without the hyphen), mortgage, medications and realty seems to have done the trick. I've also added some custom filtering into the PHP code so that they get blocked. It might be a little agressive - if anyone should get refered from doctordolittle.com or ... some other domain that contains one of the specific words that I can't think of at the moment, then they should get a "bad character in referer" error. I didn't do it for the the v[insert word here].com domains, because other than the v at the start there was nothing specific enough - vjurour, viner and v a few other things, but anything I could think of would have been too inclusive of innocents.

My referals list is now down to 13! (because b2evo ignores search engines in the normal list) Now to see how long it'll stay that way!

Update: OK, one referer snook in overnight (realantiques who were, unsuprisingly, gambling spam). Some more filters have been put in place for the more obvious and less-likely-to-block-good-things pages they tried referer spamming with.

Update 2 (7th December): Some more referers have managed to get through, but I am now blocking a much larger list while trying to keep it to a method that will block as few valid referers as possible. Each referer that gets through is a referer that gives me more of an idea on how to block them
