So I want through and cleaned out the worst of my referrer spam today. Its just fixed this month, since webalizer doesn’t rebuild a page when stats change.
I just used the HideReferrer config option with some * rules to get rid of my mortage spammers. I need a better long term solution, I think for starters im going to create a php script that is prepended on all my webalizer files and rewrite the referrer section with the nofollow attribute.
The next step after that is too look for a new stats package. Anybody got any suggestions.
