Business owner Can I get his business trouble my restraining order was granted?

If you have a restraining order and are actively seeking to cause trouble for that person, you could find yourself in serious legal trouble and certainly a target for that person to legally and successfully sue you for malicious intent

There is no one to report it to. And there is nothing illegal about operating a business when a person has a restraining order. Just move on unless he violates the restraining order, then have him arrested,

Report his business to who exactly? If you intentional set out to damage his business, expect to be sued.

Do you like poking hornets' nests with a stick?

It's a little hard to get his business in "trouble" when you're not allowed to go near it. Read your restraining order.

Sure if you want a lawsuit filed against you
