Such a useful device....
True story:
I remember on one board I frequented, there was one specific poster who delighted in posting controversial, argumentative, fatuous and utterly puerile posts; rather than contributing anything worthwhile, instructive or informative, he seemed to delight in merely flaming, trolling and generally being argumentative for the sake of it. "Ignorant" didn't cover it, so the other members got together and all agreed to put them on 'ignore'.
It took about a week, but gradually it dawned on this flaming troll that actually, nobody was responding to their posts at all, and everything he contributed was being stepped over, like a lump of excrement one sees on a pavement...
I believe he returned in several guises, and attempted to elicit responses in a likewise manner,(actually becoming more and more rude to try to get a reaction of sorts) but after a while, he gave up...
Ah, such fun... And so effective....
So, as a recommendation, if ever YOU should find yourself engaging with someone of that ilk, the above method is actually extremely effective...
