I don't get it. How exactly are you thinking of sustaining this site in the long-term if everyone can just earn for free op? Very few would be willing to upgrade to earn more thanks to this model's similarity with ponzi scams.
No KYC on top of all this makes your site even more fishy since only decentralised sites are capable of offering such stuff these days. Can you clarify op?
Things can come in a new way or dimension, if what he has to offer is what will be a center of attraction to encourage other platforms and new establishment follow same pattern, then i don't think its something bad or much of being a risk, at least they can generate alone from the traffic they stand to get from a reputable platform like this to their site and making a signature campaign will encourage for more.
