COVID conspiracy theories, vaccine "alternatives", political ads for obscure Republican candidates, stuff like that. Fortunately, at least for now there's not a lot of ads (I suspect that they can't find a lot of mainstream advertisers), so generally I only got to watch one of those ads before the video starts.

Would you still call such content a conspiracy theory?
The subtitles open with "so-called vaccine against COVID-19" and "with all this fraud that is which is being carried about by the WHO".
These vaccines have been seriously studied for year and now billions of people have taken them. Safe enough, ok?
That said, the COVID vaccines are safe and saying otherwise is kind of intellectually dishonest. Just because you can find one video where they "analyzed the vaccine contents" doesn't discount all the research and sampling data that has been taken.
If you haven't gotten the COVID vaccine, you probably should.
