The only way I would have written a factual - as in, not blatantly made up - blog post like we just read (absent basically any mention whatsoever of personal danger) is if the whole thing really took place in Southeast China, oh, and in 1996, oh and it wasn't ATM machines it was vending machines - and it wasn't bluetooth it was FM radio. With literally every detail changed. Throw in a picture of a hotel in Mexico and you're good to go.
The alternative, that he is just making all of this up, seems just so much more plausible.
I've now also watched the video. I don't know - would bluetooth signals from deep inside a machine - as you can see, in the video, the bluetooth transmitter is occluded by an entire printed circuit board - go all the way across the lobby to reach him? (as in the video)
Secondly, since it is SO innocuous to take out a cell phone in front of an ATM (I would have zero qualms doing this) to check, wouldn't this post have generated literally hundreds of comments from people checking an ATM and finding said signal? Nobody would mind doing that.
(By the way, I don't have an issue with the "laziness" of the solution he purportedly uncovered, i.e. transmitting a bluetooth device signal with the default name, as it is not obvious how to make a transmitter turn on only in response to a signal from a commodity cell phone that has nothing incriminating on it. So technologically it seems to be okay for me.)
But the whole story doesn't really add up. Someone else here mentions that supposedly he regularly reads some spammer forum where they coordinated sending him cocaine in the mail and then SWATting his house. This just seems so incredibly unlikely to me - i.e. a fabrication. How many forums can one person read?
It just seems to be made up. (Unless he changed huge amounts of details to other, similar details). But that seems unlikely.
