I agree. The only people who have said John Carley exists are Brandenburg and Opperman. We have no proof he exists beyond the statements of known fraudsters. So, as far as I am concerned, there is no John Carley.
There is, however, a Thomas Opperman. And he's been doxxed.
And you assume
he's the same Opperman...or even a real person to begin with.
A well-played Con will have fake "legit" people.
In fact. I, personally, would setup fake 'documents' for people to "dox". Tour a neighborhood, get a feel for it. So I can act like I live there....because I know of the little park down the block that was built after a house was torn down. Or the fact the mayor was caught drinking and driving in late September for the second time.
You know, the little things that only someone from the area would know.....after all, most local papers are delivered before 6 AM

Then make social media posts about those things. Set up weak passwords for those accounts so I can 'get hacked'. Maybe even go as far as to setup social media accounts for my 'fake family'.
After all, we're talking potential millions in nearly untraceable "cash" (Bitcoin). All I have to do is siphon off a lil here and there and run it through tumblers; and by little I mean a thousand or so a week. So it's more than "worth my time" to make this Con look 'legit'.
Once you know what people will look for you can easily
steer them any direction you want.
PS: Most 'good' thieves don't get greedy...instead of taking that $100 in $1 bills laying on the counter; they'll take 23 and leave the rest. --Conartists are just thieves that trick you into
giving them the money.
