Well now that you have confessed on an open Internet forum they have even more evidence.

You have nothing to sue for. They can ban you for any, or no, reason.

I don't know what you mean by "giving them referrals" but this is a matter to take up with school administration.

The time to prove perjury was at trial. Unfortunately, there are no "do-overs."

There is no such lawsuit for "mental anguish."

Can I be ticketed? I was ticketed. That's the answer.

This would seem to be better resolved but a complaint with the department. You don't seem to have any injuries to sue for.

Depending on the reasons, yes they can...........

You can let your parents know your preference.

Twitter's Terms of Service do not allow you to sue them, and you agreed to that.
