Basically what Conkers says. Some of the footie forums you can remain anonymous but you have to have your registration to join verified by the moderators, all they ask is a non web based email address on your registration, like your isp or work (if you can get away with it). Not having a profile doesn't make someone a troll, however the main character trait of a troll is the lack of a profile, so entering into a web forum debate minus a profile means the person always runs that risk of being tarred with the brush and any 'natural' comment of a controversial intimation can bring the troll accusation.

Some of the trolling at times can be amusing but in the main the objective seems to be trying to divide opinion and antagonise and at time some of the trolls appear to have caused alot of upset to folks. I remember a few years ago some porn pictures with faces super imposed on them which were hugely disrespectful and insulting, trolling at its worst
