From Timelord2o67 and his evidence, it's strongly provable that those accounts are connected to you and I don't like the fact you still can't accept it was your account. Now lemme just clarify you, if the same address is being used by 2 to 3 separate account in participating in a single bounty then your were caught this is automatically called "account farming" and is subjected to immediate ban if possible, although this depends on the bounty managers rules per their campaign otherwise, if the manager noticed it automatically they would kicked you out without notice.
Well if I may say something not pleasing to the ear, have you also understand that if your account is ban you are not permitted to make any further account or if you are being caught abusing a bounty and they are caught meaning is either both accounts got instant ban and being dropped out from the campaign without any payment and notification from the bounty manager. So you have a very slim chance for those tags to be removed if at all they wishes to remove it.
