(I was advised to post this here instead of pro. Hope you all enjoy)
As a young man I had a very troubled relationship with my dad which caused me to be kicked out of the house on numerous occasions for various reasons, most of which were me not putting up with being abused.
One of the last times I was kicked out, my friend had offered for me to move with her and her boyfriend to a small mountain town in Colorado where she would be attending college. The catch was class didn't start for a few months and I wouldn't have a place to stay in the meantime.
Her then boyfriend spoke with his parents and they kindly agreed to let me stay there until moving day. I humbley accepted their offer and they made me a makeshift bedroom out of their storeroom in the basement. It wasn't much, but it was free and honestly a place I could truly relax without fear of being chastised for the unspeakable act of existing.
My friend's BF had a little brother around my age (20ish) who at first was really fun to hang out with. We had a shared love of JDM cars, and video games, specifically racing games which made for great gaming sessions.
Little brother (LB) didn't have a game console at the time because his Xbox got the red ring, so we would share mine. I even let him download his profile from the cloud onto my 360 so he could play from his account when I wasn't home.
After a few weeks though, things with LB took a massive turn. It started with sly comments about me helping around the house, and him thinking I was better than him because I would help his mother cook, do yard work, and other small chores that he simply wouldn't do. It very quickly turned into outright hostility towards me that ended in a night of him threatening to shoot me with his dad's gun, and convincing his mother to kick me out.
I should point out that I did absolutely nothing to this guy. Even with him threatening to shoot me, I just sat there and played games on my iPod touch. When he had friends over, I was kind to them, I even helped one of his friends get a job.
The night I was kicked out, I didn't really have time to get all of my things because of how chaotic everything was. I called my friend and her BF said I could stay in his basement, but it wouldn't be as comfortable. I didn't mind and was just grateful for a warm place to stay.
A few days went by and I was able to collect my things, including my Xbox. This is where the revenge happens.
I turned on my Xbox and his entire profile was available to me. All his achievements, his game history, his saves, his cloud saves, everything! He had more stuff saved on my Xbox than I did. That's when I got the idea.
At first, I was just going to remove his account from my Xbox and call it good, but then I remembered he threatened to shoot me, so I decided to go nuclear.
I went through every single file of his I could find and one by one deleted them. All of it. Every friend he had, every achievement, every saved game, every pixel that had his name attached, gone!
I then deleted his profile permanently. Like Xbox made me confirm that's what I was doing kind of delete.
And then I waited.
A few months go by and I get a message from LB asking if his account was still on my Xbox because he was having trouble logging into his account.
That's when I told him what I did. I told him how I made sure he would never because able to access his account be it's like it never existed. As far as Microsoft knew, he was a new customer just starting his gaming journey.
He types some long threatening nonsense that I didn't bother to read and then blocked me on everything.
A short while later I was talking with his older brother (my friend's BF) and he was telling how LB went to his mom to get her to do something to me, and how he was going to fight me and all manner of nonsense.
His older brother very much aware of LB's bullshit thought it was amazing what I did. His only remarks to his brother was "fuck'em, he deserves it."
TLDR, I went scorched Earth on a dudes Xbox profile because he threatened to shoot me.
