Is this useful to police, when profiles can be forged?
Personally, when I sell something I don't want people to learn who I am. I'd rather just sell it and remain anonymous. There is more concern about the legality of a good from the buyer's perspective, not the seller.
Then you'll simply use Craigslist or a different platform for those items. There are tons more selling scenarios in my view where the non-anonymity is a comfort, not a hinderance.
They could (theoretically) request the IP addresses of the scam user. A small-scale local thief may well be using their computer without something like Tor.
