I would really hate to have to do it all over again.... but between the 4 accounts, and the sale value of the mains on the.... between T6 and S3... they 4 are worth like 2-3,000$.... Certainly not worth risking. (not to mention 2 are friends chars)
Please read our Community Guidlines as any talk of selling accounts is prohibited.

That being said your only real and legitimate option is to start over on accounts that belong to you. Even the account that you say you own but is under a different name could cause you grief in the future.
