user may be scamming in multiple areas and may even be tied to recent attempted thefts and actual thefts
1. they have or claim to have been in California (large/huge theft documented there)
2. they posted looking to buy bitcoin with cash and gave a FL number (a theft and multiple attempted thefts have occurred close to the area where this phone number's area code)
3. they have provided a name and address that match county records for that property in Oklahoma
4. they were messaging people here on forums and linking the people he contacted to "his" FB profile for further communication - this FB account is pretty new and is a member of a fb collectibles group headed by 3 other members here - The FB account has a different name than the one they provided for shipping details.
I can understand and appreciate opsec and even respect the desire to try and remain anonymous - then:
1. Don't ask people for their cell numbers
2. Don't link them to fake FB accounts
3. Don't take them out group conversations with escrow agents into private conversations on signal
4. Don't beg for money up front for "travel and hotel expenses" while bragging how rich you are - claimed to have multiple garages full of expensive cars, huge expensive watch collection, 50 acres, selling real estate in multiple states - but can't cover hotel expenses....
if you want opsec - use reshipping services and escrow services - keep yourself and your customers safe.
