Well as I as many others can probably tell you, what you've said isn't entirely true. As a black belt that was new to the forums with less than 20 posts I joined my first clan Fyre which was official. I was given a chance because of my application and willingness to prove my interest in the clan by consistently checking up on my application status, same thing with my second clan Tea. My point is it's not as black and white as belt and post count, there are many other factors such as consistency, have you ever played or talked with anyone in the clan before?, will you check on your application? have you made an attempt to get to know the clan or just pop-up out of the blue?. If you are brand new to a clan and it's members then you're just a blank face with stats, and that's where belt, post count, bans, past clans etc. comes in, because without knowing anything about you all they can use to judge you is your statistics. As you've seen at least once or twice, some people know eachother so well they get into a clan with a simple ''invite me''.
