I still think that giving your KYC is not stopping abuse, if a person wants to, they could always get at least 10 national ID and pictures from people, consider yourself, your parents, your spouse, your friends and you got yourself at least 10 and you could still abuse it. I have seen too many phome miners who do many different things like this to not really consider this as a solution, sure it would stop people from doing thousands, but it would not be stopping it for good.

Axie has the same "you can't play from same phone" stuff, so people buy like 100 cheap phones and start 100 different accounts and be scholars there and earn like 5k+ dollars thanks to that. If they want to give out free prizes, then it should be free prizes, if you keep doing "oh you should win at least x much" or "you should do KYC before you can withdraw" and so forth, it is not really free.
