I have seen many a democratic initiative ruined by trolls, bot accounts, duplicate accounts, and assholes. The best way to ensure that democracy doesn’t spiral into Haiti is to allow only financial contributors of $5 or more to vote (once the boss man has his contributions system up and running). You want to help build this community? OK, then put your money where your mouth is. To be clear, it should still be one vote per person, whether you donate $5 or $500.
Nay, This essentially turns this instance into an oligarchy. I don’t think other instances are going to appreciate this type of governance either.
Also, nothing stops trolls and bad actors from donating the bare minimum a thousand times to get a thousand voices. This would mean a high minimum investment should be required, which further hurts the common user.
I believe that a shitty/troll opinion has an artificial majority, the real users will catch on and act accordingly, however we still have to see an example of this.
I’m also certain that privacy people would rather not risk money transfers, cash or whatever (crypto is a whole other discussion).
In short, I think requiring payment, or proof of identity, or any other de-anonymizing measures would hurt discussion by excluding genuine users, even if it allows more trolls that would be ignored/dealt with by genuine users.
