The difference is when you post on social media, it is there for everyone to see and easy to distinguish. A private message is harder to decipher and we probably won't know for sure until the courts find that he is guilty of doing it. If he is, then I and I'm sure many others would be ok with kicking him off the team. Not only would he be guilty of this, but if he told Frost he didn't do it and is proven wrong, you lose all trust in him as well.
