A special badge can be provided for bounty hunters. New members must pay 10$ for the forum to get that badge to join the campaign. Already existing members and users above full member will get that badge as an airdrop. It is easy to get member rank by buying merits but for full member rank, it won't be profitable. When an alt farmer gets red-flagged to 10 of his account he or she will think twice before doing the same because it will cost him money this time.

May be forum administrator won't do anything like this because they have little interest in the bounty thread and there could be many better proposals. But If forum administrator agree then we can open up a community opinion section to gather more idea about what we can do next to get rid of these alt farmers.
