"Troll" is a Mudcat member - who doesn't go in for trolling, so far as I can see.

"Trolling" has developed several meanings, and some of them refer to things that are OK enough.

The kind of trolling that is damaging is where people post in ways that are intended to sow dissension, without having any motive over and above doing that, not caring one way or another about the issue itself.

Avoiding any subject that might be controversial isn't such a good thing. Most things that matter have the potential to divide people. But when you care about an issue, you aren't setting out to divide, you are hoping to explain your point of view to other people, and that is very different. The kind of trolls I'm talking about just want to stir things up, not with the aim of helping get a real discussion, but trying to manoeuvre people into a fight.

And nobody ever attacks GUESTs as such - it's GUESTS who don't add a handle that get asked please would they add a handle as a gesture of courtesy to make it easier for people to distinguish on GUEST from another in a thread.
