You aren't allowed to do anything against RMT on this site anymore. There is a new wave of thinking that goes "it doesn't affect me in anyway, why do you let it affect you". By their reasoning, you should have just packed up and moved to another zone.
You also have to prove they are RMT, just because they are alleged RMT doesn't mean they are. You have to rework this whole thing.
We all know RMT suck, but if you want to XP with them it is ok because you are innocent. If you get caught doing so, it's ok because everyone will support you when some asshole puts you on blast. That is, if you have any friends, I hate to assume things in this crowd.
PS: Hope GMs start doing something about this and not just brushing people off.
