I think you could, when Paul Graham was actively moderating the site, get hellbanned for unproductively pissing Paul Graham off. I think it happened more than once.

This is still true, and will always be true.

If a moderator has a button "ban", and you piss them off enough, you'll get banned.

Give people buttons, and they'll use them. Probably more than they actually should.
