The big question is who will monitor the post?
Most likely the moderators will monitor it. The great disadvantage of this suggestion is that this is very taxing to the moderators. The moderators are busy in so many things already (e.g. approving application of merit sources, recovery of hacked account, reviewing the report for ban/temporary ban, etc). If you will add another work for them, I think they will die of fatigue or over exhausting themselves.
The merit system is really working and yes there are so many things that need to improve. Just give it time because it is only in the incubation period.
Sooner or later, there will be more merit sources to help the circulation of merit. As I browse the Meta, there are so many high-ranked members contributing to the discussion and the improvement of the said system.
So let us just be patient and soon the system will be perfected.
