My BIL is a lawyer and deals with stuff like this.
There isn't a case against you so it's a complete non-issue.
He would have to file a restraining/protective order against you to prevent you from coming near him. At worst you would not be allowed within 500-feet of him or his property. But you could travel freely. Hanky was not allowed to leave the state due to probationary measures tied to his domestic violence cases against his ex.
You haven't done anything material, like physically shown up on his property, etc.
So, it is at best a general harassment charge that would get thrown out.
Hell, Brian is the best resource, as he's been arrested and charged multiple times for aggravated stalking, harassment and violating a protective order.
Online stuff like this never amount to anything, especially with the years of back and forth bullying he's done as well and threats to end your life a hundred times.
