He’s not trying to stop blogs from mentioning this - in fact, he likely wants the opposite - the more blogs mention it and embed the video directly from his YouTube channel, the better. Again, the goal isn’t to stop mentions of what happened/what was said - the goal is to funnel the views to his YouTube channel.
If you want to know how basic YouTube monetization works, you can just google it and it will give you a surface overview of Adsense, YouTube Partner Program etc
Blogs are threatened to stand down when they publish what are likely things that have been disproven and/or libellous things without corroboration or citing sources. In this case Vlad is simply interviewing a guest that said “abc” and “xyz”. Their issue would be with Blueface rather than Vlad. Could they make a request for him to take it down? Yeah, possibly - that doesn’t mean he would. Vlad is a dikkhead vulture, but he isn’t some run of the mill blogger - he has one of the biggest hip-hop related channels. More importantly, that isn’t seemingly the case here because again, the videos have been struck from random accounts on Twitter (things that affect his pockets), but is up and accessible on his YouTube page (where he makes money)
