You find any censorship there, you let me know. The wiki is open to anyone to edit, and the logs would clearly show if someone started screwing around with it, and the logs are also open to view.
More knowledge base is good, though, so I don't mind seeing another one spring up. Anyone who plays Perp is an involved party, btw - and if you think Wikipedia doesn't have censorship and manipulation, I have an oil derrick in New York City for you.
Ninja edit: FWIW, we deliberately included a section for corps to describe themselves as a way to hopefully encourage others to get in there and edit. We really wouldn't mind other hands in the mix. There's a lot of game here for one corp to document, and we surely don't know all of it.
