I'm sorry, I don't have much time.
You were saying that you had very specific measures. Your technology cannot detect content that had to be removed either by your moderators who saw that it was child pornography, or as a result of a request from someone claiming that the content was non-compliant and had been made without their knowledge.
What technology do you use to ensure that content will not be reposted, content that should not even have appeared and been removed because it had been flagged?
