Well, I started the thread because some people talk about trolls as if they are all law-breakers when it's clear they're not according to the law, so I'm talking about the law. i'm not talking about good taste or double standards or my own opinion of what other people say. Sorry!
No need to apologise, the problem without any thread involving numerous different people is that we will all be talking over each other and the subject will usually branch off down different paths.
I gave as an example of "what is trolling" our own resident troll Wonderfulspam. Some however class him as a WUM rather than a troll though I think one of the defining characteristics of a troll is that they exist to wind people up, so I'm not sure that they aren't one and the same thing. I don't think Spammy is a lawbreaker, just a not-very-funny distraction, mostly. You don't have to break the law to be a troll, and I'm not sure who these "some people" are who you claim believe that all trolls are law-breakers.
