I'm not a fan of KYCs. However, as per the agreement, they wanted a means to ensure people do not abuse the reward. They figured KYC would be the only possible means of avoiding abuse of the reward by just 1 person.
I couldn't suggest a reasonable alternative. If you can suggest another means of removing rewaed abuse, I'll try to get it implemented.
I wonder how KYC connected with blockchain activity. If you go to the bank to ask loan or something like that you have to do it. But what connection between blockchain and my papers, issued with country authority? ) Anyway I don't remember any project with KYC, that not become scam sooner or later.
