Most trolls are just antisocial behaviour. A troll with an ASBO? Mesa gotsa badga 'onna!
I don't think so. Net trolls don't usually like to expose their own identities to scrutiny, which makes online boasting about that kind of thing difficult. And nobody in real life is going to be impressed. Net trolls either have no friends in real life or, quite often, behave quite differently in direct personal interactions, where there are consequences from being a complete
twat.
