Note that the worst, and most sophisticated trolls will just keep a second well-behaved account to monitor the actual forum as others see it; so it won't be more powerful than a ban to them. Forcing you to 3) as you say. Someday we'll have shadow banning deluxe - not only will the troll be seeing a different forum, but they alone will see fake A.I. generated responses to them that will cause the troll to waste endless amounts of their time continuing to troll-debate. Time they can't spend buggering around with someone else's forum. Sadly, by that time, we'll also see A.I. auto-troll-programs appearing in large numbers.
