I was playing Black Ops 1 with some friends, it was throwing connection error so we switched to Black Ops 2, a friend who's pc is bad did not join the game, after that I restarted the launcher and it came out that I was banned.
As I thought that the ticket would be answered later because in latam it is 12:17 at night I created another account to continue playing with my friends, which caused the ban time to increase.
I translated it with deep l, so forgive the spelling mistakes.
