Scam?

Yes, your first thread was deleted. It was in the exhaust forum and not in a Parts Wanted forum. Now, as far as the scammer, it is entirely possible the scammer posted on another members thread and they reported it. Often times, I delete spam accounts and there are other accounts with the same IP address. (same person, different user names) When I delete one it deletes them all. If you get anything suspicious, hit the report button and let us handle it.
Mike - Reporting to FABO the second such email I've received this month . . .

My Gmail inbox listed an incoming email from "For A Bodies Only M." (notice the "M." at the end. When you hover your cursor over the sender, it says "[email protected]").
The subject line says "McNair67 started a private conversation with you: "'71 Duster 340 Exhaust Manifold" (I did post a parts wanted ad this month with that subject line).
Opening the suspicious email shows a "view this conversation" button, but when you click on it, it takes you to a FABO page saying "the requested conversation cannot be found".
I did a search in FABO for member "McNair76" and found nothing.

If it would help FABO admin, I can forward the suspicious email if you can provide me an email address to forward it to. Thanks, Dave
