Because near everything about this appears to be a low effort scam. The gmail is to add to the "authenticity" of the scammer being 16, because this way they can add a presumed birthyear, wheras with domain email it would make no sense. Proof is in that the address [email protected] is avaliable, which would be the first thing a reasonable person would have tried, before adding the year like a dickhead.
