Certainly. Their experience would allow them to recognize a lot of covert signals ("dog whistles") which would not be obvious to other viewers.
The same goes for pornography. There's a lot of weird porn which gets away with being on sites like YouTube because it's too esoteric to be recognizable by most reviewers. For example [NSFW but not explicit]: https://www.youtube.com/watch?v=BWW8_8fc0-E -- there isn't any exposed genitals or sexual activity in the video, but it's clearly made to arouse people with the right fetish. (Just look at the comments if it isn't obvious.) A reviewer who's familiar with "weird porn" would likely be much better at recognizing fetish material, even if it's a fetish they don't personally enjoy.
