Frankly - SE will never ever manage to deal with RMT spammers - that's just a nature of the "game". The only possible solution would be if SE itself would actually sell gill in game. Where is a demand there ALWAYS will be a supply - be it official or unofficial - so why not make it official instead, get rid of RMT for good and make the money in the process as well? Will it ruin economy? Who knows - most likely yes in a way but at least we'll not spammed by all those RMTs like now who're ruining it anyway ...
