Idea 1) No, this is how it would work (OP updated). It is a social media platform, users don't have to do anything except posting content if they want:
That is exactly what I meant... They post their usual stuff on your platform and other users have the option to tip them instead of liking/upvoting and this tip comes from
token issuers who want their token distributed. I do get your idea but it can be exploited pretty easily and doesn't ensure a fair distribution of the tokens. Fair distribution is a hard problem to solve without KYC... There are certain ways to limit 1 account per person but they all have their shortcomings... I still don't see what value it brings to the table besides being a middle man in airdrops... Anyway, Good luck with it if you decide to pursue it...
