I really don't see what all the fuss is about, you can still buy diamonds from players, and can get everything you really need with that. Especially if they activate the NPCs, then you can even get house energy -- but really, house energy isn't the end of the world if that is the only thing F2P can't get.
As far as what is bannable, that also seems very obvious the way it has been stated by GM Nytefall. Don't try to sale anything in-game for anything outside of game. Basically keeping all of the economy of the game, inside the game, makes sense and is really the only way an MMO can work and not be extra flooded by scammers/spammers/gold-sellers. If the only personal gain a person can get from playing RoM is *inside* the game, it is less likely to be exploited by outsiders. If gold sellers could only buy in-game items with the money [stupid] people pay them, they wouldn't do what they do. They do it because they get REAL money.
I'm not saying this will stop gold sellers, but the rules are still good and should be there. Otherwise it is like saying we should make murder legal, because the law doesn't stop everyone from doing it, lolz.
I really get tired of seeing the people that are quiting RoM trying to sale gear, gold, their toons, etc.. either for real money, or for items that can be used in other games. I mean, how many times (on Govinda) have we seen people buying RS gold, and shouting over and over about it in world. Will be nice if the new staff is going to crack down on that.
