Just had someone send me my information via XBox from a game

Incase you’re wondering, had a little fun with the Snipe doc build. Build didn’t work. Tunneled the hell outta this guy (He was the obsession) and this is what I got back. DBD can be crazy as hell sometimes.

Just to be clear, you don't have personal info somewhere freely on the internet that someone could find by searching your gamertag would it? If not, I'm curious to know how this guy got that info.
@GT_Legend2 I got the impression he did it every game.... Check his rep.. it's avoid me.
I also know that he also brags about throttling his killer's net... It's really messed up and I don't know why this guy hasn't been perma banned on xbox.
I hope you reported him.
Report him for threatening you as well as invasion of privacy. But just to be safe you should call somebody who handles the bans and stuff because this guy literally hacked your account and you have proof that he did, sure he could have guessed but if his guess was right that should make you call someone.
I would also try to see what you could do for your own safety like if you can sue them or not.
