Harassment problems

She is your ex and they are her friends.

Why do you care about the IP? Move along and get on with your life. Use the available methods to block unwanted interactions online.

Don't respond. Boredom will set in and they, too, will move along and find some other way to entertain themselves.

Don't care about your ex any more. It is all about moving ahead in life. Good luck

dude.. just do not get bothered. Go a head with your life.........
