Bounties IMO are mainly social media focused or at least should be. I won't allow a company to use a bounty for their signature campaign. That must be ran on a bitcoin paying basis only to prevent some of the useless spam that bounty campaigns create with running signature campaigns in them.
Firstly, I don't get why would bitcoin-based campaign generate less meaningless spam. How does that work?
Secondly, if you don't like the idea of signature campaign and you believe that it'd be better to forbid wearing signatures up until Full Member rank, than why do you keep running all these campaigns and allow "members" to join in?
