it has been said "if thine eye offends you, pluck it out" but that is both catastrophically stupid and ineffective.
it's also self-defeating.

far simpler is to add such a person to your IGNORE list and suddenly the sun comes out and birds sing in the trees, and the sense of foreboding each time you log in evaporates.
it's then left to the staff to delete posts (such as death threats and libel) that are illegal or legally actionable. deleting this sort of thing is entirely consistent with First Amendment, by the way.
