Because the rule has always been about one player trading real world currency to another player for in-game goods, because players don't own in-game items. Those are Jagex's property, and by RWT-ing you are selling things that aren't yours and making money off somebody else's intellectual property, which is illegal.
I am willing to admit you got me here. In that case there is nothing that fits it more than calling it real world trading.
Yeah that is a legitimate reason for calling it real world trading.
For example if I own a movie on DVD or Blu-Ray that only means I own a physical copy, it doesn't mean I have the rights to do what I want with it.
The same applies to RuneScape membership.
I no longer feel they're hypocritical. It was my mistake to not see how the discussion three years ago ended. But can you really blame me? Nobody feels like digging up old posts to see that.
I'm glad we are beating this dead horse again
Don't worry I'm done.
