I basically said this before but many of these chiropractic videos are in a very special and subtle category that has plausible deniability when it comes to the obvious (to me) pseudosexual advertisement aspect that it primarily benefits from for viewership. Very very sneaky. Very exploitative too in a way, but then again nobody's putting a gun to these females heads that be on these videos with these airbrushed painted clothes on being felt up for half an hour for millions to see.
I imagine a large majority of them are participating just for the clout and exposure. It's a pretty popular category on YouTube after all.
You know a lot of BS is going on when every single patient gets the exact same procedures done to them in the exact same order all the time. As if every single persons unique problems have the same solution. A lot of these YouTube chiropractors talk a good game as well. Good salesman. They can talk and ramble about this or that and make it sound good for 30 minutes.
