I think "why" is a great question, but I don't agree with your (perceived) assumption that a good answer for it isn't forthcoming. I also agree that a good AMA is a very rare thing, and I'm with you - I'm not about to make my own AMA either.
This person might not "teach" you a skill you didn't have, but they also have a different path and perspective which may be interesting, or resonate with other teenagers. Or it may not. Of course to you, it may indeed be completely useless, but I wouldn't then assume the whole AMA is useless to anyone that reads it - just to you. So I'd argue the best thing to do is live and let live, and don't post at all. If it turns out you're right and it wasn't a great post, it'll peter out on its own without any help. And if not, you might get a good read out of it. The "inclusive" solution is to allow it to be included, with or without your stamp of approval.
When you posted, did you actually think OP might come through and change your mind, or were you just signalling you didn't think it was possible? That's the difference for me - the former I'm on board with, the latter I think we can do without.
I do appreciate your willingness to hash this out, though, and I think it's great that you express yourself directly - we usually need more of that, not less of it. I didn't mean this to be a "pile on Pavel" moment, I think Ben was right in pointing out that there's nuance here the system wasn't equipped for. There no "right" answer here, but increased mutual understanding is always good for the comunity.
