It's really tough to see toxic players in our community, I've long felt our community to be better than that. Unfortunately, you're always going to have bad apples in the pile though.
In terms of being against rule breaking - I don't think they'd have much power to do something unless its outright harassment. However, I do agree that could be very damaging to someone that is suffering from mental health. A lot of people with mental health problems use video games as a escape and it worries me for them to come across that kind of behaviour.
