In that I will totally agree, but not in the case that they give you the approval and let you work until you reach the threshold and then ban you. To avoid that they should make a detailed observation of your publications and evaluate if it suits them or not, then send a PM with the result of the evaluation and your approval or rejection.I believe this is exactly why most forums don't allow you earn from the very beginning, as they would give you some numbers of post for them to check if you are up to their standards.
