Cant one of the mods just block this mongs IP address and stop him from posting drivel? Perhaps then the lad might finally pull his life together and get a job in the real world rather than spending all day trolling on rumration.
In the grand scheme of things however, contentious or antagonistic posts can actually enliven forums & stimulate contributions. Like 'em or loathe them, Norman, Hig & Nailz (who are each in invidual classes of their own & in no way comparable) certainly get people posting.
Alternatively people can stimulate interest by simply being downright amusing & intelligent with it - step forward MLP....
Potentially, potentially not. Factors to think about; easy to get round IP blocks, IP range blocks can cause collateral damage by blocking other legitimate users, similarly blocking a shared proxy has the potential to block other users.
the only way to really deal with trolls is not to feed them.
This, lookit lookit! Don't reply and they'll get bored. Of course, if they post in lil's then go to town, gloves are off and trolling can be amusing. I just object when they ruin Current Affairs or the serious topics.
