This would be the ideal solution, to somehow force bounty managers to 1) set some rules for quality 2) force enrolled members to post according to the rules.
But nobody can tell how we could force those bounty managers...
Bounty managers don't have an incentive to stop spammers: they pay a fixed amount of made-up Tokens. If ten times more people join, they just all get a smaller part of the pie, but the campaign gets more exposure.
I really dislike Tokens: it's Ethereum's way of taking market share from Bitcoin by spamming social media for their own financial gain.
I'd love to see all campaigns with payment in Tokens banned from the forum. If campaigns are only allowed to pay an actual amount of Bitcoin per post, they'll be forced to start caring about quality.
