It seems to vary from one RMT group to another. Some will keep sending /tells to the same players over and over again until they're banned (which can take SE a very long time to get around to). Others seem to only send a couple tells to each player and then stop, presumably to recycle their character to a new name that's not on as many blacklists. So it helps with at least some of them.
