When my post have been deleted I havent usually received an explanation. Occassionaly I get an email letting me know. In general the only common thread, no pun intended, is that the posts are negative about Omagine. Positive posts are never deleted, as far as I can tell. And, I'd say there is an obvious bias. I had small running squabble with Alton who posted a fairly nasty reply and only after HE said it should be taken down did the powers at be do so
