Seedly people generally likes to encourage enterpreneurism, but i have the following concerns. Some concerns here. 1. Is it illegal or grey market? 2. Is he spending money on this pursuit? Or buying ingame currency or cryptocurrency with cash? 3. Is he likely to get scammed or preyed upon? (Money, or socially) 4. Is he spending too much time on mining and farming to create these accounts? If the answers to all of the above are no, then should be fine. But honestly idk anything about this market, so perhaps you should try and find someone who has experience. As to your customers' ethics, don't overthink it. It is not your responsibility to police their spending habits. Your concern can actually be applied to all products sold by merchants, whose ultimate aim is to get people to buy their products... consider toys and kids' games.
