Plutonium

FutureRave This isn't my second ban.

Hey, I was playing on black ops 1 with a friend and when he got off i was scrolling through the plutonium forums and i found someone talking about a black ops 1 mod menu that works in singleplayer, it sent me to an external link (github), i downloaded it, i ran like an exe file i believe and it automatically injected without me pressing anything and i was like oh crap i read the anticheat forum and it said no injecting and then i log on the next day and im banned,
if there's anything that can be done, i'd appreciate any help.

it also may have been that i had OBS open?
i've just read a forum that someone got banned for having OBS open
