This have been discussed to many times, but for those who are reading this for the first time- DO NOT DO KYC FOR BOUNTY.
Red flag is that they are attempting to collect kyc data on their own website ,this is just absurd, dont go for that.
If their are legit, they will use respecting KYC company to do this work who will protect the data.
Mate, there's purposes why other bounty campaigns required KYC for bounty participants to get the bounty rewards. First is we know that there are many member are cheaters by using multiple account. If you don't want to do KYC it is up to you, find the project that don't need KYC.
