Nick Mamatas, editor of the excellent online magazine Clarkesworld, has over the last week banned several authors from ever submitting again, as featured in banned author exhibit one, two, and three (and for a special encore, author exhibit three responds to the banning on her own blog). I'd suggest people submitting to Clarkesworld or elsewhere read up on these exchanges because they are very educational with regards to what not to do when submitting your fiction. Nick also has some helpful suggestions on how Clarkesworld handles author revisions.
