This is pat we are talking about. He likely thinks if he can prove they are all elite stalkers who want to harm him, he can also claim the legal case that went against him is in the wrong, and in fact is only furthering the harassment.
Not to mention, he can likely sue some people. Its free money, and anytime someone tweets something at him that he does not like, he can just point out how he beat his stalkers. Likely run a little game on that as well "how I beat my nazi stalkers because of my amazing social rights activism, you can learn my secrets in this series of tweets."
I was going to say he could write a book about it, but we all know how well he is at putting out work. Even thought podcasts, but the lazy shit would just tweet about it. He loves his twitter with all his heart, its the only thing he sees as bringing value to his life.
