Because of the threads that said the Wiki was down, I looked at the Wiki again and found this:

http://www.opserver.de/wiki/index.php?title=Special:Recentchanges&days=30

As you can see, a lot of spambots, similar to the ones we occasionally see at the forum, put spam messages on their user talk pages. Although the only way you stumble across these spam sites seems to be the Recent Changes page, maybe you still want to do something about it?

I know. There is no method to automatically remove spam bot from this Wiki version, unless we protect it with a password or something like that. But we'll update to a more recent Wiki version in the next months, which will hopefully solve that problem.

same with the forum spammers / Pram- /baby carry bag posters...

There is a link "get paid to take surveys" under the "Documention" section right on the front page. However, even I can't edit the front page.

How the hell did the bots get it there? Can some admin remove it?

I removed it. And I didn't need to be an admin to do it.
