Have you checked the campaign didn't require participants to retweet the same post? You really should include the UID name as well as the UID number, it might jog people's memories. A few of the accounts you list haven't "moved funds". Have you checked if the actual outbounds are exchanges, or gambling sites?
Not really, there were also tweets from other users at the same time and they were different from what this group of accounts was tweeting. And about accounts, that haven't moved funds: that's clearly how it works, he accumulates tokens and then sends to one of "main" addresses. But the manner of writing the same + same tweets + joined in the same bounties.
