User blog comment:Mathmagician/Editors - Dealing With Vandalism/@comment-4511886-20120121095122/@comment-4674838-20120121100242

The wiki was actually like that once before, back when there was obscene amounts of vandalism. The thing is that, overall, logged out users help the wiki far, far more than they hurt it. They fix small spelling mistakes. They add trivia. They contribute new information to pages right after a new patch comes out, etc. So we don't want to prevent anyone from editing =)

Vandalism is a minor thing when you compare it to all the positive contributions people make, I just emphasized it in this blog post to raise awareness. By the way, thanks for visiting this page.
