Plutonium

I was playing origins for the first time ON customs and I wanted to mess around with a mod menu being a idiot so I downloaded https://youtu.be/am2RxsQtvmo this because why not and it didn't work -_- shocker right? but I was banned for 13 days I think even though I tried using it in customs solo... alone... by my self I know I could just wait to be unbanned but I'm way way way impatient for that BUT anyway I thought that you were allowed to mod solo games but I was wrong I tried an alt but shocker... that got banned as well I just want to play zombies please tell me if I'm not allowed to use mods in custom if I'm not my bad sorry but I just want to be unbanned... Oooooh just looked ok so I didn't know I was supposed to use lan mode I just downloaded it about 3 days ago sorry
