And I say the same things in those situations:
Stop being a victim.
Ignore the offending poster(s).
If they still talk crap, who cares? They are showing their true character by acting like a junior high kid. (And I know there are more than a few of those around here.)
But by ignoring them, it does not affect you in the slightest.
You choose to control how you let others affect you.
Stop giving them so much power over you.
