Most of you don't know who I am, I presume, and if you don't, don't ask, if you do, you shouldn't care, but I must say: I have seen Jagex do similar things to curb autoing, account sales, gold exchange, and other things. (Case and point: removal of runescape classic) Each of them has caused large amounts of legit players to flip 'em the bird and walk off - either permanently or for at least a year. So when people say they will leave, I wouldn't take for granted that they don't sincerely mean it.
