Unfortunately, the "No trolling" rule is one that the forum very rarely moderates.
This is the sad reality , that's why sometimes i don't Blame those ANN Thread that created as Self Moderated because of this Troll Abused in which taking chances to Ruin Good reputation, though I Believe that "You Cannot Put a Good man's Down" yet we can't deny the fact that trolling can damage in some ways the good reputation.
This isn't an ordinary troll who will get bored when they don't get the attention they seek. It's a psychotic criminal with an agenda.
That's it its Either face them and let them taste the bitterness of their own medicine or keep silent and be attacked forever.
