This new scam is getting more common in crypto, is called "Reputation Scam"
where a site is targeted by scammeres and they create posts on forums, facebook, twitter, etc, and then they contact the site and ask for money in exchange to remove all those posts from the internet, this scam is very old in amazon accounts where competitors left bad reviews on their competitor products.
It looks like people are genuinely upset over being locked out of their accounts after KYC was suddenly sprung upon them. An exchange can't with-hold peoples' coins just because they didn't pass a newly-implemented KYC system. That sounds like fraud. The only thing they can do is not allowed them to trade anymore. Not allowing them to withdrawal? That seems criminal.
Also, making cartoons that suggest KYC is cool is pretty lame. So is insinuating that people who don't upload ID are 'ashamed of their origins.'
