Here's a serious suggestion for you Jagex.
Every company is about making money, if your CEO isn't thinking like that, you better kick him out, lol.
Anyways, This update will kill your little moneymaker for sure, banning people from the forum or muting them ingame cause they riot, will only put oil on the fire.
So there are 3 options that i see:
1) Up the trade/drop limit to for example 100k, maybe even make it every 30 minutes. It still would stop the goldsellers.
2) Sell gold yourself for a lower price as those RWT do, makes you earn more money.
3) Stay hardheaded and sell your servers
