> if you post a picture of your face and say "I beat cancer!", you're getting upvotes, and there won't be a single comment in the thread along the lines of "this is a picture of a face.

objectively, and putting aside the kneejerk reaction against being fooled, i cannot see a single thing wrong with this. no one is asking for money or trying to con the audience out of anything tangible; either they're telling the truth about the cancer (in which case they'll be happy for the upvotes) or they're trying to game the imgur community for upvotes (in which case they'll be happy for the upvotes). you might argue that that's cheapening the upvote, but the sole value of an upvote is what you, personally assign to it. you want upvotes that are worth something to you, post in a community where they are rare enough for you to feel they are worth something.

as for the rest of it, if the backpatting keeps them happy, what's wrong with it? it seems infinitely better than e.g. the cringe-oriented communities who get their social bonding and dopamine hits from making fun of the more earnest sections of the internet.
