While it's true that we shouldn't tag members for bounty abuse without very strong evidence of connections (which hasn't be provided so far), you as a bounty manager still have right to remove someone from bounty campaign at your own discretion, right?
We all have principle we follow which is why we're different as individuals. I respect your opinion and decision you would have taken if you're in similar situation so please do the same to mine. Some of the accused have some decent decent merits earned for their posts after looking at those from the main post. They also have some decent posts that should earned them reward assuming this accusations wasn't brought up, that been said I cannot go pushing them when they haven't broken any of my campaign rules (atleast not confirmed, we're just speculating).
Better the guilty get set free than pushing the innocent, that been said my decision stands but since we already have them under our radar sooner or later there'll be a mistake that'll most likely exposed them and they get punished.
