There are some edits among these screencaps that are by a few IPs, but I have reason to believe these IPs were Xkeeper, just not signed in. The reason for this is this IP reverted vandalism on Xkeeper's user page, stating it was his. Another also shilled jul (then known as acmlm), a forum software he programmed and advertised on his main page.
First off, after getting butthurt with the admins over pages being deleted, he "retruthed" a page by blanking it and marking it as satire.
When this was reverted, he proceeded to "rm*" (if you don't speak autistic dork, that means wipe) the page.
He also proceeded to add his own opinions on how Wikipedia handled things elsewhere.
He got very opinionated about how Wikipedia picked and chose what to keep on their wiki, and was upset his irrelevant inane bullshit wasn't tolerated there (which, knowing the shit wikipedia writes about, should tell you something)
When he was told off for his vandalism, he proceeded to respond... well, how you'd expect. I won't bother screencapping all the blanking of his user/talk pages (which he had a habit of trying) as well, but one example is included for good measure.
Sounds like he's always had a problem with bots...
