How CoD4 modders ruined my game

I was given CoD4 by my grandmother a few years ago for my birthday, and I decided to play it since I was bored.

So I put the disk in, and start playing. The very first match I join is a modded lobby with this one guy who had god mode, flying, colored text, unlimited ammo, etc. I stayed, since it was kind of fun. Then I left. I go to find a different match, and the next match I join is another modded lobby. I kill somebody and get -2e1035139 experience. Which basically means infinite. And I repeat, NEGATIVE experience. I eventually leave the game, and for my single and only XBL account, I couldn't join any CoD4 matches. At all. All the gamemodes said "Unlocked at Lvl. 1" and I was a Lvl -1. Within 15 minutes of putting that fresh copy of CoD4 in my Xbox, it was ruined.

Thankfully I didn't care much about the game, so this was pretty hilarious lol. Thanks for reading :P
