Anyone who suggest KYC in cryptocurrency space shouldn't use cryptocurrency in first place and keep using fiat (exception for centralized exchange and few merchant). I would rather leave this forum rather than give my identity.
Even CloudFlare implementation is enough to make good member who want preseve their anonymity left this forum.

If we want to prevent spam, scam or merit farming, disable signature and remove bounty child board are better option.

TLDR : Your idea can go to hell.
