What can I legally do if I was banned from social media for life?

I did nothing wrong. I have this social media account for 8 years. They banned me for life and refused to return my intellectual property photos and contact information. I am going to sue the social media for 1 billion dollars. I need an attorney who knows how to do this. I am the ambassador to the United Nations for the Hebrew Israelites and I could not go to the United Nations to demand the reparations from the indigenous people’s forum on permanent issues because Facebook had all of my information. I can prove damages to about 1 billion dollars. Maybe we want to sue for more. They violated my first amendment rights according to the Supreme Court case which was decided June 19th 2017. Three justices did not comment. The vote was 6 to nothing in his favor. I am an innocent man but I am a registered sex offender. I am the ambassador to the United Nations. This should be a slam dunk case. Supreme Court held that you cannot ban registered sex offenders from any social media. This social media banned me while the case was pending and they knew that it was pending but they thought that they would win. They did not win.
