All the photos show is that someone with that name had a RYTM.

He may have been the original owner of a RYTM that was bought by the scammer. Or, just as likely, the photo was just downloaded to be used by the scammer - with no connection to the Mr McDonald at all.

Posting the photos is useful because now they are linked to this thread and if they are used in a future scam attempt, a reverse google image search will ring alarm bells.

When asking for photos as proof during a transaction, ask for the seller to include a handwritten note in the shot - with the date or some other detail that you request.
