One possible solution to RMT would be to make it so you can't use anything besides /say (and Novice Network) until level 21. Why? This forces the RMT advertisers to use a paid account. This means, with each account ban, they WILL lose money. This will unfortunately give them incentive to just steal an existent account, which means increased hacking incidents/sabotaged accounts. Further security precautions would be necessary for the user upon login to keep their accounts secure. There does currently exist security measures that take way too long to bruteforce and have a mathematical 1-way encryption, tho obviously account-sharing compromises that too.

As for making the gil buyers disappear, I think that may be way harder. Gil buyers are often discrete about it, and while you can try to put filters that put users who may have bought gil on high alert, it's a far more scattered problem.

Alternatively, (or additionally) do what WoW is doing - allow players to buy gametime for resale for gil on the marketboard. They do not choose the price, the system automatically chooses for them. Gil buyers now can "buy" gil legitimately without the risk of getting banned.
