Done the same (left negative feedback and supported flag). The bounty criteria is also questionable as they require participants to buy their tokens (minimum of 10 SUNTO ~$10) before they can participants in the bounty campaign. Also when a project start their ads with calling other projects scam and theirs legit just as they have done on their bounty ANN, the case is always the opposite & also a red flag to investigate further before patronizing such projects.
The Project looks scammy to me although I'll be willing to withdraw my feedback and support for the flag if they can prove otherwise regarding the OP's accusation (but i doubt that'll be the case). Anyways, good job OP.
Can you write more clear, why you find project looks scammy? Look at official statistic: around 90% of bounty projects leave the bountists with nothing due to fictive stakes and token price drops. We pay real project tokens immediately after bountists have done their jobs, tokens can be sell on exchanges immediately. Entry fee to bounty program is a good marketing step, peoples will write quality posts. Entry fee is temporary disable. If you was greedy to pay a bounty entry fee, you can join us for free now and get real money, until that option will be enabled.
