Remove all examples and ban LinkedIn in your code, so that it can't work with LinkedIn. If you have a LinkedIn account, delete it. Problem solved. If they sue you, do not spend every dime on an attorney trying to fight them. Lose. Then declare bankruptcy immediately and protect your assets. LinkedIn can suck it. Also, don't be afraid. It costs them nothing to send a S&D letter. It costs them a fortune to sue you, for which they can only achieve some extremely unprofitable satisfaction. I would even send a copy of a notarized letter to them telling them to stop contacting you. Do it every time they contact you. On their fourth attempt to intimidate you, go to a magistrate and request a restraining order against them.
