IIRC, isn't there a monthly target to hit in terms of diamonds for Live Pro? Could he actually be hiding something else and that's why it's been taken away?
1 Mill diamonds or 600 active subscribers in the last 30 days according to this, but it does also say your live content will be reviewed to see if it meets community guidelines and is 'worthy for you to be a role model', but given the likes of Diadro, it's probably more about the diamonds.
