I think this quote kinda sums up how these RMT people work VS the measures in place.

"The problem with making something Idiot proof is they always find a better idiot."

Meaning, no matter what measures get put in place, they will just work that much harder to find ways around it until the game is so locked down no one can play. Honestly, I play almost every day and in the last 6 months i think i could count on one hand the amount of RMT's i've seen / been spammed by, and my blacklist is under 10 people. Some of you guys must have some of the worst luck ever to have full black lists that you dont manage and constant streams of RMT bots spamming you.

I hope things get better for you.
