i say that they should just have the selection of rather than "blacklist" have a "report RMT" option. I figure this would expedite the process of doing what ever they do to RMT. On SE end i think when this selection is made it copies the message that was sent whether it was a shout or tell and send it to the GM and that way they dont't get people doing it to people to just get them in trouble. Sort of ensuring that no one gets tangled up in any sort of collateral damage from just some blind RMT reporting.
