Well, within today's legal system, social media are responsible what's posted on their site.
What makes matters worse is that comments get disabled aa does sharing. I can't even link to the problem. If I report the ad, it is there again tomorrow. It's almost as if that counts as interaction worthy of trying the ad again.
I personally don't like RB. I find the whole act to be off-putting. Though that is most often a sign of others liking the content.
I don't think letting the "reason" go unchallenged is responsible given the above.
Of all the people demonetised by YouTube, already rich man can't profit from allegations of sex offences unless he can find brands willing to pay him directly has to be one of the least sympathetic.
