After giving loads of suggestions in-game, through support center, and here, the only response I got (besides from some fellow users who are as mad as I am about RMT and SE's lack of action) was being banned from the forums.
Instead of hearing the complaints of hundreds of players and doing something about it, Square-Enix chooses to do nothing but silence whoever complains. Where are we? North Korea? Cuba? We can't talk about the problems anymore? And we don't deserve an official answer from Square-Enix?
It's not like we are begging for a favor. We are actually paying for a service (to play and enjoy the game). And as far as this service goes, it's one of the worst I've seen.
The social side of the game is beyond crippled. We can't stay logged in without being /busy, or else spambots spam and friend request us every minute.
I'll probably keep playing until Heavensward comes out. That is, keep playing it as a single player game (tells disabled / busy / unable to communicate properly). After that, I'm done... won't keep playing this game to be treated this way.

If you want to be lawful neutral and ban me from the forums for having told some inconvenient truths, then BE lawful neutral and ban everyone buying and selling gil daily. I'd gladly accept the ban if I knew it would be done to the ones really breaking the game.
