Plutonium

I got banned for no reason. I was playing with my friend, trying to get in a custom with him ( i didnt figured it out ) and suddenly i got banned. I installed the game yesterday and ive played like 5 games. Didnt cheat or used anything illegal. Just used the "unlock all " tool on the command line. I dont know what i did wrong. I just played some games to test it out and played 1 or 2 matches with a friend. Later on I logged in again and i was banned for 7 days.
I not gonna lie that after I saw that i was banned, i tried to log-in in a different account and the ban expanded. But I Still dont know what i did wrong.

Resxt That’s the point, I don’t have any hacking tool on my pc or I didn’t tried to inject anything in the game. I don’t even know how to do this kinda things btw. The account that was banned first was Vulgo Caio, but I tried to log-in in a different account that the username is Caiolechu and the ban expanded for 14 days.
If u could see what I did wrong pls tell me. I really didn’t downloaded anything to hack the game or anything. I was just trying to figure out how could I play with my friend in a custom game, and I couldnt figure it out.
