I think this forum also has something similar that is called merit system that is intended to reward good quality content although merit system needs to be simplified like anyone can give any amount of merit and it should be like what likes are in fb or claps in medium or upvotes in reddit so my point is that one should not be required to have merit to give merit.
I do not see that happening on the merit system. Aside from being a reward system, it's also used as a measure to reduce spam. If forum admin/s will allow it to be easily given, we'll probably see more people joining here for the sake of signature bounty and will just spam the forum with low quality posts.
