The registered wiki user "Drunkers" (yes, the spammer scripts not only spam anonymously, they also create real accounts lately!) spammed several pages in the wiki, adding tons of spam links, hidden with fancy CSS and other tricks. Nothing unusual so far.
Another registered user ("Mootlif3") reverted the spammer's changes with comments like "reverted (spam)", "unrelated links removed", "deleted spam links", and "damn spammers". Or so I thought.
The real "wtf" moment emerged when I checked what "Mootlif3" really had done. He didn't really revert the changes of the spammer. He only removed a few of the links from the page, leaving most of them still in there! So it would look like a nice (human) wiki user had helped out with cleaning spam, but in reality he only created a false sense of "security" for people who really want to clean the spam...
Damn spammers, indeed.
