They admit in the leaked emails that they don't review all flagged videos, they means they knew some content was left online even if some of it was CSAM or revenge porn.
Did you even read your own link? They entered a deferred prosecution agreement so they wouldn't have to go to court, they didn't plead guilty but they acknowledged their responsibility, the charges are still valid for three years.
They're still being sued by 62 victims that filled reports of content of them being hosted without their consent to which Pornhub didn't react or replied by telling them to fuck off.
Unless you work for them I honestly have no idea why you're defending them like that, it's a huge corporation in a field full of abuse victims, there are actual ethical porn, don't pretend like Pornhub has anything to do with ethics.
