I don't, however, agree that if Shawn had acknowledged the situation it would have been taken as an admission of guilt.
The statement that was put out is an acknowledgement of the situation.
As I have previously said, just because something is not illegal does not make it right. A lot of the reason why this has been broadcast around social media is because people believe others have a right to know if someone is creepy/untrustworthy. There is plenty of evidence to show that one individual has behaved extremely inappropriately, and as such the only way to prevent this happening further is to let people know about him.
Spreading unproven rumours can land you in serious trouble under the term of "Defamation of Character".
