Due to some old posts has been deleted from time to time. Minimum post of 15 are going to become 20 or more because some bounty manager are counting the total post minus the previous week posts. Though you posted 25 post in one week, sometimes if you are unlucky you will not receive stakes because the total posts are less.
Do you agree that bounty manager team must count only the recent posts in the inclusive days of the week?
I'm exactly facing your problem, I was really wondering why I didn't get my stakes for certain months, then I went to check and I really noticed my posts were not in the numbers I was sure they were. It was like 3 weeks after.
