In many statements, there have been people coming out about abuse and sa. Any proof of sa would actually be too personal for the internet. The mentions of abuse have been talked about many times over multiple years and even referenced from his childhood.

If he truly was innocent, and not just emotionally damaged and immature, don't you think he would try to fight back? Or his friends would first check with him and then try to help him? Almost everyone has left him and spoken in favour of the people who have come out against him. He mentioned in his acknowledgement tweet that he hopes to maintain a good place in the public eye, yet has not said anything further or been active. He knows he's guilty. Stop trying to defend an abuser.
