I doubt that these newbie bounty manager accounts are really operated by beginners.
The Bounty Manager account, called OP, only posts related to the projects being handled. Even though they are online quite regularly, there are no discussions regarding projects or posts on other boards that support the bounty manager's career and reputation on the forum.
I assume the newbie account with the Cooper member who is the bounty manager is operated by someone who is used to doing this. This is just an assumption, there is no incriminating evidence yet. but from what the bounty manager does and the attitude of the bounty manager. clearly shows unprofessionalism.
Your assumption seems to be very correct. I also believe that this account is not operated by beginners because the posts are made only for Bounties and not for anything else. This means that this could be a specially created account, and of course, there are other accounts that are also used to accompany it. but it is difficult to provide more accurate proof of this assumption.
It's very clear that activity still occurs frequently on this account, even though it's not used for interaction. It's hard to know what is being done and for what; let time tell.
