Oh for God's sake - I'm sorry. I went to bed for a few hours: Wake up, and there's three reported posts and threats all over the QF threads!
Labia, Dear - I cannot ban somebody from posting because you have threatened to lose your temper and throw a hissy fit if I don't. It doesn't work like that. JBM is certainly being provocative, and I expect he's rolling around laughing at the way you're rising to the bait! What he's doing is not particularly clever, but it remains within the rules of PPRuNe. If you lose it, and go posting abuse all over the forum, then you are likely to become the only casualty.
So Don't... Ignore him/her: Rise above it. You are bigger than that.
JBM - You've had your fun and you've made your point. Now go and lie down for a while and cool off.
