What if he's not logged in? And what is your opinion about banning him? Should Jimbo ban him?
If he's not logged in, a sysop can ban his IP for vandalism or other egregious Wikipedia rule violations (Wikiquette, NPOV).
I don't really see his contributions in those categories. If I'm skeptical, Jimbo will be doubly so -- in 2 years of Wikipedia, we have only really banned a handful of logged in contributors. Lir, Clutch, 24, Helga Jonat. With all the Lir pseudonyms it may look like more though :)
If you want to make a case for banning the buddha, better start collecting evidence of - violations of NPOV -- "the French stink" - violations of Wikiquette -- "you stink"
Collect these in a file, preferably with the URLs to the specific diffs, and send that to Jimbo. He'll probably get back to you a couple of months later and ask for more data ;-)
