Unfortunately, the way you went about this and promising to pay upfront, probably means some of these accounts aren't connected, and the users who messaged you might of been there to scam.
The end result in either case is a negative rating. Unless you mean to imply that we don't tag attempted scammers? Almost all of these account are surely connected. I need more time to process the whole list.
Attempted scammers should receive a negative, at the very least the accounts that messaged were either looking to scam, or looking to participate in what many would see as an unethical practice. I think an in depth look into the alternative accounts needs to be done though to see if there is any other evidence supporting this.
I agree with you that almost all these accounts, will be connected and controlled by the same person, but due caution needs to be taken to assure that they are.
