Look at whaleshares for a donation system. It hasn't been the best. People see the staking rewards they get as "their's" and not everyone is going to be participating. Our current system defiantly isn't perfect, but it has incentives to vote(maybe we can add even more incentives to vote for others, ex: reduced reward for selfvote).
You're comparing apples with oranges and whaleshares was flawed from the start. Bad example. 😕
They'll just create another account.
