This is directed at Jimbo in particular, and I apologize in advance if I'm not following the proper procedures and such. I'm not a sysop or anything, just an ordinary Wikipedian.
Khranus, as is discussed at great length by me and others on Wikipedia:Problem Users, has a history of adding conspiracy theories to articles. A mild such theory is that dolphins may be triggering cold fusion with their sonar, and that cold fusion is proven to work but is being covered up by, among others, the British royal family. He also likes to use personal insults aimed at users who disagree with him on talk pages. See early revisions of [[Dolphin intelligence]], as well as [[Talk:Cold fusion]] for examples. Or just see a random edit out of his contribs, it will probably be a conspiracy theory, a personal insult, or both. On [[Talk:Cold fusion]], he actually cites a co-author of the Illuminatus Trilogy in support of his claims.
This is just a summary of what was posted to the Problem Users page about Khranus, and I'd refer everyone to his section on that page for more information.
Thanks!
