Just thinking how many we've had. Off the top of my head: Vlado Bozinoski, Massimo Luongo, Andy Petterson (twice, for one night only both times if I remember rightly), Andy Bernal. No others spring to mind. Oar number five?
Think that thread had rather got out of control. I agree with the OP's original post, there is no need for discussions to turn into name-calling, regardless of who is involved. It's not debating the issue and it doesn't help board harmony.
Clearly there are certain users who have repeatedly been asked not to post abuse and still do. Think we're pretty fair in that we give people a chance rather than just banning them straight away, but one or two users pay no heed and I don't think they can have any complaint if they are banned.
Similarly, the board isn't helped by people deliberately winding others up, dragging up rows from the past etc. A month or so ago the board was somewhat less fractious, not really sure why things changed. Perhaps we can go back to that.
