According to the BPIP profile page for the account in question, the account was autobanned, at least several months ago, and hasn't been "active" since July. Although I'm not sure exactly when the autoban happened, I don't foresee it doing much scamming. (edit: was banned for copy/paste plagiarism)

Also, OP claims there was an address under his signature which was deleted "years ago" which he could sign a message from. In 2014, 2015, 2016, it appears to have only been "have a nice day!" in the signature (reference), sometime in 2016/17 it changed to an address - the same time it became branded with this "Luxury" marketplace that this person is now hoping to use to recover the account... I don't think this account is going to be recovered anytime soon.
