Maybe before giving a high rank, like up to say black belt, the person has to post a video of his practice/fight or whatever they do as practice, so you get a better idea where they are at before giving the high rank. Anyone can talk a lot. One video speaks a 1000 words.
The rank is given to encourage people to post. More posts = higher rank.
Positive reinforcement is the addition of something meant to increase the frequency of a behaviour. Higher rank is expected to lead to a higher frequency of posting.
We should not assume that the MT rank confers authority or martial skill.
I ignore the MT rank.
