This game developers are very afraid of RMTs, that's why they taken out of easy method of earn Gil or reduce of earning.

This is silly, SE. RMTs has been around for many years. Even Runescape still have them! Nothing can stop them. Nothing! Even if you mange to prevent RMTs from send tell spam, they still will always find way to spam.

Question is, will you nerf or taken out anything in order to stop RMTs at all cost? Then it is pretty oblivious you care more about killing RMTs rather than improve things that need an improvement.
