I did respond.
I elaborated on what I wrote in the email. I said I don' think he's a 'bad' guy. Although it is possible that he is, I said I think it is more likely that he is simply misguided.
And I do think there could be some truth to that.
I said I didn't trust myself to not throw caution to the wind, and get myself involved with something dangerous.
I told him I didn't buy the story he gave me of how he has come to know this millionaire pornographer.
I told him that the fact that he became alarmed when he thought I had done a background check on him was a red flag.
This guy obviously can't take a hint. I had to essentially tell him that while I'm not entirely sure he is a 'predator', that I no longer trust him.
I did not admit to knowing anything about his criminal record, which as far as I know only amounts to that Halloween incident.
I even denied knowing his last name, or what his specific address is (I do in fact know both).
Thankfully, I was also able to block him on the Messages application.
