What I wrote in the comment box pretty much explains it. I open the wiki, go to place a match result, and find that I'm logged in as Demagog. Whose password I don't know (nor care to >_<), and whose account I've never been logged in as.
I don't know if it's a fixable glitch, or if it's very very rare glitch with the software, or if it's an unfixable glitch though.
Edit: I'm really not sure what's going on. I tried logging out, did so, logged in as PuppyChow (it even says "Howdy, PuppyChow!" on the dashboard...), went to go post a match, and it still says I'm logged in as Demagog. So I went ahead and posted the match because I wanted to see what would happen, and I got logged out and the comments page appeared to go back to a past stage (it only went up to ufc's match post directly after mine). Then when I refreshed the page, all the comments were back (that part is probably just a cache problem), and my comment was posted by PuppyChow. So yeah, what the hell is up with the screeny then?
