Nobody is comparing you to a scammer. Your account has been part of a sold account circle in my assumption to which these previous accounts are connected.

Two different accounts posting the same address means only one thing. They belong to the same person. This world is not so kind that someone else is going to do bounty work to pay the money to your account, here everyone earns for their own. Besides both the links were found on signature campaign/bounty campaign applications hence it is also less likely that you were trading coins among yourselves.

This is pretty much a solid proof that you are belonging to same group which has been discussed here. If you have any other evidence supporting a rebuttal do provide the same. For now the flag remains.
