Like I said previously, there's a way to mitigate this through notifications. After all, we can't possibly spoon feed everyone, otherwise the interviews, and podcasts would have to be censored in fear of spreading misinformation, but that isn't the reality. I'd like to think that people are more inclined to research a shady looking Youtube video, than believing something just because their favourite infulencer said x is good. I mean, you only have to look at so called privacy conscious Youtube channels promoting VPNs which are no where near privacy conscious.
Or perhaps you can you link them to this thread in all the video descriptions now that it has a big ol' sticky on it:
