It is my general observation that if someone is posting 10 times per day (even considering that they dont have a job or family or any other commitment which is highly unlikely), it is still a very high number.
A carefully crafted post with no errors and proper formatting takes about 2-3 hours. So anything above 4 posts/day is really a no brainer and points to the fact that the author is just pushing out content just to earn more rewards on each post and has no intention of posting quality material.

Thank you so much @cabernet for the wonderful comment ^_^
