Thread:Project:Support desk/Stopping persistent manual vandalism?

With a combination of blacklists and other anti-spam extensions, we've been able to essentially achieve 100% protection against automated spammers, but unfortunately persistent manual vandalism still gets through. The only ways we can think of to defeat humans who vandalize is to use CAPTCHAs or $wgRateLimits/abuse filter to slow them down, but that's the problem - it only slows them down and it's not a very good solution. Does anyone have a more effective solution at stopping people who manually sit there and vandalize, typing in CAPTCHAs and changing IP addresses? Any input would be much appreciated!
