Eh. Today I just saw that somebody posted the same kind of content (a number for support service of a well known Windows antivirus software) in the bug report form.
We've had them post organizations related to it as well, in the web system. Since the organizations are moderated, and they can't submit news or events until it's approved, they never got any further than creating those. They've also posted doc comments, which are also moderated.
The unique thing about the wiki is that we allowed them to post things without moderation. (even the lists have moderation, depending on subscriptions and spam scores)
