Also, very old information needs citing. After all, anybody could say that there was an explosion in Club Penguin back in '05, yet there was nobody back there to confirm it. Most of us users are a year old on CP, it's good to have some sources to confirm stuff that we can't with original research.

And again, original research is sourcing, uploading screenshots, SWFs, everything counts as sourcing. It's a very organised way to maintain the wiki.
