Referer spam

Lately I've been getting a lot of referer spam: hits to web pages on the server using spammy HTTP_REFERER URLs. Most of them for some reason are hitting non-existent scripts and pages, but there are a bunch of them hitting things like my photo galleries and such.

It's gotten to the point where the Referring URL stats collected by Awstats is pretty much useless because all the 'Links from External Pages' is nothing but a list of spammy URLs.

Not entirely sure what the point of it all is. But I'm not the only one.

I wonder if there's a way to tap into the MT Blacklist database to block them. Something I'll have to think on.
