If you do piss anyone off, keep records of everything. Make sure you know who they are, and where they live, before you start doing business with them. This lets you send the police after they hire someone to DDoS you. Bad people need to be removed from the pool to reduce these sorts of attacks. Record 100% of your phone calls. Android has free apps to do this for you automatically. If you're in a state that requires 2-party authorization, move to a state that offers 1-party authorization. Sanity in laws = freedom of citizens.
