Does anyone have a geocities rule that catches most of the spams
and has few FPs?
after looking at many of these, I ended up just giving 4 points to any
http://*.geocities.com/*/? (written as perl expression of course).
together with Bayes and other tests, this seems to block all that spam
(I didn't need to block all the geocities.com URLs).
FPs are theoritically possible, though I didn't see legitimate geocities
pages with the "/?" pattern.
- A large number of these come from IPs with no rDNS
- many come from Asian networks.
so it may be good to mix multiple checks together to reduce FPs.
