Not quite sure what those other charges have to do with this particular case (maybe I didn't comprehend the entire article) but this is stupid.
There are security tools on your profile for a reason.
For one, she could easily block him on Facebook. She wouldn't be able to see him and he wouldn't be able to see her.
How was he able to like something she posted if he wasn't already friends with her? That would mean everything she posts is available to the public.
Why not take extra measures, especially online, to make sure that restraining order is even more in place?
