You can't sue for cyber stalking. It's a criminal offense. You have to convince a district attorney to file charges, which would waste a fuckton of taxpayer money on your feefees. The wiki page I linked (repeated here) summarizes the identifiers of cyberstalking much better than I can.  Actually, most of the key elements of cyberstalking read like a sjw playbook - posting personal info, contacting employers, threats, establishing unwanted real-life personal contact.  Mocking hams just isn't on the list.
