It's not what the player thinks, it's what the parents think. Do you want your mom to see people writing bad words on the screen?
My mom really wouldn't give a shit what people on the internet say to be honest.
And juntalis, noobs would just be like "omgz hez winning so much hes a hacker voteban voteban voteban"
It's still a good idea for younger children with parents who does give shit. Also, voteban is a must.
