Hi,
online players are sometimes strange animals. Some use rude words, insult, drive backward. Some are really mean, racist, homophobic, explicit. It's life, anybody seems to have the right to mistake freedom of speech for hate speech, unfortunately.
But then it might be wise to tell parents their children should not play STK online ?
Or maybe a way to turn off the « chat box » or to « mute » some people ? Not a ban, just an option somewhere to not show this or that people's comment…
