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?
Most of the bounty manager here does not rely on the last post counts. They are well informed about the pruning of topics here in bitcointak.org, so they do not rely solely on the recent post count minus the previous post count, besides how they can check if your post is constructive, spam or on the right board? They check them individually and manually. Probably those who do this kind of stuff are just new managers, inexperience of what really happen in this forum (talking about deleting of topics).
