Our current "reputation score" can be renamed to Popularity and we keep it more or less as it is, a popularity index and nothing more.
We indroduce a new Reputation score and everyone starts with Reputation 100
Flags/Downvotes cost the double voting power.(Downvoting 2 times per day consumes the same voting power as upvoting 4 times)
Flags/Downvotes can always reduce our Reputation score but a regenaration hapens daily.(maybe high SP can accelerate the regeneration of our reputation)
Accounts that downvote a lot and rarely upvote must have a harder time to regenerate their reputation. Also Trolls and Villains that are downvoted by too many accounts and with a high SP/account ratio, must have a much slower regeneration rate and at some point it should be impossible to regenerate at all.
This new Reputation score must be a huge factor in the weight of our Upvotes and Flags/Downvotes. A reputation of only 1 gives our votes or flags a 1% weight power of our vote, negative reputation hides any posts we make. If our reputation regenerates, our old posts we made with negative reputation stay hidden/greyd and are not affected.
Posts that get more "Flag power" than upvotes stay Grayed/hidden, no matter what the reputation of the poster is.
