getting banned from using lockers at school

my school charged us to use lockers so instead of buying one me and my friend group decided itd be easier to just make someone our bitch and put all the stuff we dont want in our bags, sweaty gym clothes, rotting food etc in some poor kids locker. this went terrible for him but excellent for us until i left a wet towel in it after swim prac which then moulded all the paper and books in this kids locker. the stench became so unbearable the teachers launched an investigation as to where the smell was coming from, the kid get caught and proceeds to snitch on us. rip the communal locker.
