An "ignore" button is fine, as far as it goes. Of course, if everyone ignores their posts, trolls typically interpret that as a sign that they've won the argument, so I don't see that as stopping them from sucking all of the oxygen out of certain threads. If we have an "ignore" button, then we should also have some way of noting (perhaps on a member's information page) just how many other members are actively ignoring him/her/it. That way they'll know how many people can't even see their posts.
As a more immediate remedy, I'd suggest deleting the troll's posts --
all of the troll's posts. Banning trolls merely forces them to adopt multiple personalities, usually
seriatim but now more and more simultaneously. Banning, therefore, doesn't stop the trolling, it just delays it briefly until the troll can adopt another alter ego. Wiping out all of the troll's posts, however, discourages the troll from coming back under a new guise, since there's a good chance that its subsequent posts will also be deleted.
That may be a drastic solution, but, as I said before, this is a virus. You don't negotiate with a virus.
