It can still be used to artificially pump up an idea. Or used to bury one.
This is the problem. All the algorithms are based on the upvote count. Bad actors will abuse this.
So maybe more weight should be put on comment count? Much harder to fake those.
So, the question becomes how do we rank posts and comments in a way that is not based on either upvotes or down votes or number of comments? I could see a trust value being made for each user based on trusted users marking others as trusted combined with a personal trust score, but that puts a barrier on new users and enforces echo chambers.
What else could be tried?
Only if trust starts at 0. A system where trust started high enough to not filter out posts and comments would avoid that issue.
Maybe instances should be assigned a rank for how dependable they are. Length of time active, number of active users... Stuff like that and each instance keeps track of its own rankings for each instance it is federated with. Put the upvote and those stats in a magic box to calculate the actual upvote value.
That's where all the harm comes from
Agree. Farming karma is nothing compared to making a single individual polar-opinion APPEAR as though it is other’s (or most’s) polar-opinion. We know that other’s opinions are not our own, but they do influence our opinions. It’s pretty important that either 1) like numbers mean nothing, in which case hot/active/etc. are meaningless or 2) we work together to ensure trust in like numbers.
