| | Sam Ruby: Wiki Spam Update |
 | | Using nofollow in a wiki is really worthless and actually does more harm than good, so you'd be better off implementing some better server side filtering (perhaps a Bayesian filter combined with a few other techniques) so the spam doesn't even get published. |
 | | We run a wiki and haven't really had too much problem with wiki spammers, apart from one persistent guy from China who occasionally comes in and added dozens of links to about 10 pages every few weeks. |
 | | Since almost all the spam appears to be done manually rather than by a robot, we added a sleep(20) to the code before printing out the error message denying the edit - that should be frustrating enough for a persistent spammer, while hopefully not too annoying to a legitimate submitter getting it once. |
