I don't get it. Why didn't he make a professional sounding user name, maybe put a line in his signature about who he is and what his business is, and post like anyone else does? People respond a lot better to that approach, kind of like the guy from Ultimarc or Oscar Controls. People usually would rather buy from someone they "know", and that is readily available on a forum to answer questions and address concerns in public.
Of course, most likely, he doesn't give a flying flip about arcade machines or MAME machines, and has no interest in learning, and just wanted to cash in on the fact that people in this hobby buy a lot of T-molding. I wonder if he has made any similar posts on general woodworking/cabinetry forums or whatever.
Before "busting" him, the folks here should have pressed him for details about his alleged "MAME cab", lol.
