I don't have a good experience with bounties on btctalk, plus I just see all the fake profiles chasing signatures, idk. I really like the bounty this one betting platform made. They run it themselves through their website with a leader-board. I can't remember the name, I see so many projects every day, its' hard to keep track... will look for it, though.
that's the tradition of bounty campaign from the beginning in this forum, some even have up to 20 accounts to follow the campaign, it is ridiculous but that's the fact.
