People currently are worried about possible abuse with the positive merit system, add negative merits, there are many more angles for abuse and malicious actors.
This is however just my opinion and expectation.
What I could get behind on the other hand is giving a few people the ability to terminate single merited posts.
We could call this group "merit patrollers" (the quickest way would be giving sources the option, but there could be an independent selection forming another group with different users).
This should be a limited ability both in availability (users allowed to do so) and volume (every patroller gets X terminations per month).
Terminations carry more weight than regular merit, and should thus be further limited (the average source size is ~200 sMerit per month, so termination could go at 10% of that, 20 on average).
What do I mean with "terminate"?
Right now, when I come across a post that is obviously spammy and was merited, I cannot do anything about it. I might spot someone farming merit with their alt account, or just giving it to spam posts to troll.
I can report that, I can investigate that, but I cannot do anything against the action itself, directly.
I might give the people involved negative trust for abusing the merit system, but that is only an indirect option and shouldn't be utilized, imo.
The merit is given, the result stays the same. I'm powerless there.
This is a huge difference to the trust system (I dont like that comparison, but it seems near), where I can counter positive ratings with a negative one and the other way around.
So what if I could counter merit? I don't mean giving demerit directly, but rather reversing a given merit rating from other people.
The way I could see this work is that when we have a spam post merited by one or more people, merit patroller have the option to terminate this post.
The merit received (and the sMerit) would at this point be taken away from the user that wrote the post, but not given back to the sender (as a punishment).
A termination would be shown right after the list of merits collected (example "
A termination would also mean that the post can no longer be merited.
However, termination are specific to posts, you decide that one post shouldn't have merit, not that one user shouldn't have it
