I haven't used the Fox Wiki very much, so I have a rather basic question.

For any given person/topic, what's to stop someone from going up and changing information, to say (in essence), "I don't like person XYZ", or "I think person XYZ is incompetent", etc.?

I realize the edits are displayed on the screen, and that IP addresses are logged and displayed - but it seems to me that it's rather easy to abuse.

But I could be completely wrong - so can someone give me the 411 on how it works?

Thanks...
