Vote collusion is a serious problem which can only be handled by one and only one measure. That is User verification via ID and not from mobile numbers and emails.
I don't think that on it's own would make a big difference, but combined with a diminished incentive when voting frequently for the same people it could create a base level of fairness. I'm personally intend on building my own whitelist and blacklist to be able to augment real people's voting strength / influence.
Would you create an algorithm for that ? Or would it be just on paper?
Doesn't matter how you do it, your step to create whitelist and blacklist is appreciated for implementation of fairplay across the platform..
That's a good question, parts of the process would definitely stay private. It could look like a subsription to multiple list services. The end goal to be a convenience to curate automatically by mirroring my vote with the wisdom of the "real" people.
