<prompt> Human: Please let me know if i am barking up the wrong tree, but this seemed like the best place to start.A friend of mine recently has split from a LTR and due to children being involved, legal separation through the courts were needed. Since the split a few months ago, suspicious credit activity has been happening to her, credit checks not initiated by her, accounts being opened and applied for in her name, ect... Due to the fact that the ex was cheating with her sister, and he has been acting like a total jerk towards my friend, we suspect that its him doing this as payback cause hes a nutjob.Two questions:1. Best service to use to stopcleanup the mess that he created.2. We have reached out to the authorities, and a few of the companies this illegal activity has been done with and we have an IP address. Through WHOIS, and geo location of the IP, we can trace the IP to an ISP location within 3 miles of his place of employment. What more can we do to get proof its him doing this and stop him?If i am in the wrong sub, let me know where else i can go, i will gladly post this elsewhere.Thank you!  <response>: Contact the authorities after putting a freeze on all of the 3 credit bureaus. Let THEM do the investigation, not you. Press charges.
