From what I gather... The Bounty payments are effectively being issued as part of the ICO... So that makes the bounty payment recipients participants of the ICO.
For the projects to remain on the right side of these (ridiculous) regulations that various jurisdictions are starting to impose on ICOs, all participants must complete KYC.
The fact that you disagree with KYC does not magically free SYNCFAB (or any project) from their legal responsibilities.
- Does it suck? Yes, of course...
- Should this requirement have been made clearer? Possibly... It's hard to know when they actually realised that bounty participants would need to complete KYC. If they knew prior to the campaign start, then they are at fault. If they found out at the completion then it's really just "bad luck"
- Does it make SYNCFAB a scam? No.
Perhaps SYNCFAB should consider a good faith payment of equivalent ETH or BTC to the participants who don't want to complete KYC... Given that the goalposts appear to have shifted so late in the game!
