Image quality is terrible. Either they're using a really crappy camera or adding some really shitty grain effect in post production. Or is this a standard thing done by thots in the hope of suckering paying punters?
He is probably a new guy doing onlyfans stuff. And men who likes crossdressing have a harder time than women. So new camera will take some time. But even with a modern smartphone the image quality shouldn't be that bad. And as you said: The added grain effect and other filters was a bad idea. But maybe he doesn't want to get recognized or something.
