Post History

Unless something is clearly and directly abusive, let it go.  Letting a trolling post get downvoted to oblivion is way better than any mod action of removing or otherwise censoring it.

People know crap when they see it.  Let them vote accordingly.  Not only does that get around accusations of mods censoring what they don't like, it's a much stronger statement that it's a bad post when the whole community says so.

For bullies and trolls, peer pressure is more effective than mod pressure.

If you feel insulted by some bully or troll, consider why you think it actually matters.  Grow a thicker skin.  Get over it.  If it's unfounded, other users will likely defend you by downvoting the post.  That's more effective and elegant than feeding the troll.

(As an aside, the specific post you refer to was mishandled.  The question was getting severely downvoted, and a few answers explaining the situation were highly upvoted.  The system was working.  Even after the user self-answered, there was really no problem to fix.  Editing out his suggestion about being appointed CEO of Codidact was the wrong move, and partially played right into his hand.  When trolls make absurd suggestions like that, they only make themselves look stupid.  By deleting it, you deprived others the opportunity to see what a troll this user was, and in some way legitimized the point by taking it seriously.  Just downvote and laugh it off instead of feeding the troll.)
