Sluffy, you often make a rod for your own back. The trick to beating abuse is not to bite back. Not only you fall into the trap, a few others do the same.
Abusers hate being ignored, or made fun of. I treat Nuts like a playground. Some posters I'll get on with more than others, due probably to a similar sense of humour or outlook, but to the outside eye it might look like a clique, though this isn't intentional.
I've given you stick myself, but I've always tried to do it with as much humour as possible, and with tongue firmly in cheek, and you've always taken it in the spirit it was intended.
My own view is that if people want to post abuse, let them do it. In the end they'll be found out by other posters, who'll get thoroughly sick and tired of it.
Biting back once or twice is all well and good, but if it continues it simply becomes a sausage machine, with the abuser happily turning the handle, and the abused supplying the meat.
Ignore them, or laugh at them, and they'll soon get tired of it.
As I've said before, Nuts is very much the Bash Street Kids in forum form, with you our long suffering teacher. If you leave us, what might happen?
