I'm pretty sure that this person is not "stupid" in the sense that he can't read the flag contents, but just really really rage-quitting - although it doesn't help that the platform is shady as hell.
I doubt it. You know how the saying about getting free publicity goes, he seems to be revelling in the glory of the attention he his getting even though it is all tarnished with negativity. Right now both of his known accounts ("unlimitedmoneygenerator" and "GluttonyY") are associated with spamming and trolling as well as being known for offering ways to make unlimited money therefore by default is a scam too.
I've seen a lot of trolls spurring with us over the years, and many flags were dished out, but I think I can recall only one instance of the troll supporting their own flag against them. So it's a really rare occurence.
