Can I know why I am not even in the list? I have submitted my application, fulfilled all the rules, and I am still not in the list? Seriously ?

I really want to know how the rewarding system goes, and also what is that, that I did wrong while I was submitting my application?
Done with the signature, done with the posts, had over 15 in one week, no spamming and still I am not on the list.

I just want an explanation how the reward system goes, and why I am not on the list, what did I do wrong ?
thank you for the answer

I saw the Round 4 Signatures and I saw people that are not even paid but they are on the Bounty Round? As for me I am not even there ?
can I know why ?
thanks

I had a change of signature because I made higher rank.
