I like that you want people to persuade others to join, but I don’t think you’re clearly thinking it through. Making a system like this would take work from the techs, which could be spent doing something more meaningful. It seems too complicated; considering we can just promote player to be more nice, make sure players are not being toxic, and fix games. Lastly, 10k per person would be a straight kill to the economy. The economy right now is a tad inflated, and that would hurt it more.
The only pain in the backside are players with a VPN, instead of receiving money players could obtain cosmetic items instead.
