Dear community,
A year after discovering DNM I've finally run into my first dispute with a vendor. The package never came and so we are in the dispute process and he has asked me for my user names on other markets (to prove I've ordered from him before I guess) I'm not totally sure what difference it makes but I wanted to ask the community if there's a possible OPSEC issue with doing this. What if this vendor has been compromised? Is giving him my other identities safe?
He probably wants to check the PGP keys are the same to prove your history. Honestly? I don't think it's all unusual. When I signed up to C9, a vendor wanted me FE because I had no history on there. I explained I'm not a noob to DNM's, just to C9 and once he'd matched my PGP keys, he was fine with staying in escrow.
