And thats why i see trains of characters with names like asdfg running through towns and receiving 2-3 /tells a week from them offering me gil at amazingly low prices. Yeah really sounds dead to me.
Legit players sell gil to websites which in turn market it back to players.

This has been going on a while, as even though there comes a certain point where gil flows like water, SE has done a fair to decent job of keeping that out of the reach of throwaway RMT accounts; the only other way to keep the flow of cash going without the contributions of high-level players at a low risk of being banned is account-hacking, which SE has done an AMAZING job of combatting simply by incentivizing the purchase of authenticators to the point where you really can't justify not getting one.
