Simply, KYC is scam if you think it is always used in scam purposes.
Know your costumer is a step to know more about them in order to exclude the scammers as long as possible. KYC purpose depends on what the motives of the team by implementing such process.
Your right but for bounty hunter i think kyc is not needed..only for ico investors.
It still depend on the rules of the team, because as far as i know a lot of cheaters on a bounty campaign so I think KYC is one way to block those cheaters and greedy to earn money. KYC can be use against us, so make sure that you will just participate on a good project, its the risk on this cryptomarket if you cant handle it dont take it.
