DDoS from party

Just been booted offline for around 10 minutes from someone I was in a party with (affecting my whole house) reported the guy to Microsoft as he exposed himself in messages and I think he has been banned as all the messages of him admitting to it have been deleted like what happens when they swear in a message. I was wondering if there is anything else he can do with the information he has as he is not gonna be too happy with getting banned.
