It is not a thing last year as it is rare to see some projects that require KYC and now it is normal for them to put KYC for $100k - $200k bounty pool even for the airdrops which is now commonly not profitable to waste time, what's wrong for me with the OP's complaint is that the campaign announced that it is not required then suddenly they change the rules to require the week before the end of campaign, they should bound for that rule even if they fail to raise the hard cap.
