Instead of banning gil sellers or not banning as the trend seems to be, introduce a bounty hunter system that allows players to attack the offending seller in question. Of course, the player in question would need to be a verified gil seller.

Ideas:

1. Bounty payout based on number of blacklists offender is registered on
2. A reward system for annihilating a certain amount of gil sellers, eg. 10, 50, 100
3. Successfully killing the gil seller marks for deletion.

This would do wonders for clearing away the massive amount of spammers from our blacklists. It's unrealistic for SE to expect the players to report each individual seller they come across, as is recommended. Allow us to actually take action against these offenders, show us you mean what you say in your ToS, allow us to do a bit of extra work, reduce the workload of your staff and compensate our time with a little extra gil.

Please comment below, this is how ideas get turned into code. FF Community, ASSEMBLE!
