I've had numerous wiki run-ins with the Grump on Cold Fusion / eCat.
(but I haven't edited BLP)
Apart from his anti-fringe-science posture, he's a stickler on
reliable sources. (ie none of the sites covering the ecat are
reliable, so there's nothing to report).
BLP's complaint about censorship is invalid -- connected contributors
can't change the article, and there are no reliable sources reporting
on this (yet).
The main charge is that he (I'd have to check the history) repeated a
libelous comment from a (wiki) reliable source, and should have known
that it's false.
