If we can tackle campaign managers, we have solved half of our problem so my suggestion goes like this. Before a user gets a privilege to manage a campaign he/she must have a past record of been meritef for quality posting e.g a Legendary member applying to be a campaign manager must have earned 50% of the current legendary merit requirement to be eligible to manage a campaign.i.e user must have earned 1500merit for equality posting. This will make then take their job seriously as they can lose the privilege.
I don't think merits is the right metric for this. A (signature) manager should be able to distinguish between quality post and garbage post, but it doesn't get reflected on their merits. For example, one of Indonesian local moderator (which is also a bounty manager for some projects in the past) doesn't have 1500 merits, simply because he's too lazy to make a post and instead focus on tackling our reports. But his judgment is good, better than maybe most altcoin campaign out there.
Secondly, there should be selected altcoin used for altcoin bounty campaign payment. I am against the idea of banning all altcoin bounty leaving only paid bitcoin signature. The forum has grow more than just bitcoin. I believe that's why we have grin as a payment option now. So this is my suggestion, every altcoin bounty should pay their participates in the token of the blockchain their project are developed on.
Example, If your project is based on ETH or EOS blockchain and you want to run a bounty campaign participates will be paid in ETH or EOS and not your worthless token. I believe this will also have an impact as they got something to lose if shitposters are been paid.
I honestly doubt they will be able do that. It's much profitable to give their tokens that were created out of thin air for payments.
