Spammers exist everywhere. It's just that MediaWiki by itself doesn't have great anti-spam protection systems and even though Wikia has several tools to try and combat it, the spammers just get wise to the problems and find ways to get around the filters. What you may not realise is that much of the spam these days is done by human beings, who can pretty much defeat many anti-spam systems designed to stop robotic spam.

Whenever a user posts spam on any wiki's I manage, regardless of them doing it elsewhere, I immediately report it to VSTF and don't bother touching it.
