My question was based on the presumption that the person was a seller, not buyer. The problem would be that Dammitt may have posted blockchain linked addresses, sold one or more of the accounts in question, and Dammitt was subsequently banned.
Right, and Aqualung89 continues to use that address in his profile because that's just how account farmers roll.
I can understand your concern. Some of your farmed accounts got permabanned too so it would be in your best interest to sow doubt in such cases.
Sometimes expecting mothers try to be nice to others, and make an effort to be an overall good person. I understand both of those things are difficult for you, but you should try that.
I am not sure why Dammitt was banned, but as far as I can tell, the other two accounts have not caused any major problems or trouble in the ~6 months since Dammitt was banned. Assuming whatever Dammitt did to get banned was not especially disruptive, I would suggest moving on.
