If you were just talking about it in yell, and never actually went through with it, I think your account should be unbanned since you technically didn't break any rules. I know people have spoken about buying/selling RS gp in the help cc before, and they just get told that it's not allowed, not outright banned immediately. Sorry, but it seems whoever banned you was a bit trigger happy, hope you get your account back soon.
Thank you Thorru. And it seems I have already had my name tarnished. People already think I did RWT. I actually never traded anything at all...I simply yelled about it. This is the first time Ive ever been in trouble for anything on here. Guess some servers just have trigger happy mods ready to ban in mere seconds. You will be missed my friend.
