In reply to Martin W:
Sounds remarkably similar.
I guess that most people can spot the banking scams very easily now, let alone the Nigerian princes, so scammers need to be a bit more sophisticated in their targeting, giving at least a plausible story and some appearance of personal connection. I imagine something similar is being done regarding cycling, swimming and dozens of other specialist interest areas, to catch people when they are a bit less guarded than with the well known, generic areas.
A while ago I remember the fake delivery scam, when you supposedly had to get an unexpected parcel from Parcel Force or whoever. That seems to have run its natural life now, or perhaps it was never very successful.
A red queen arms race between the scammers and the punters really, lets hope they don't get genuinely hard to distinguish from real transactions.
