Did you notice MKBHD said this kind of embargo is a "red flag". Well, he already knows any issues that may exist, so it's very interesting that he chose to say this.
FWIW, he does talk about CSAM and is definitely aware of its pitfalls on his podcast, so it's not like he's blindly banging the drums.
Besides that, I'm sure his reach on Social Media & Youtube is quite a bit larger than on his podcast. And I guess, the reason he had those comments under his videos was, because those people don't listen to his podcast either.
The fix was to slowly scrape all the fluff out with a needle (I am sure there are better ways).
This is of course assuming your issue isn't anything electronic.
