Woah. I've gotten a lot of responses to this, and can't exactly reply to all. So I'll add in a few key factors. Firstly; usernames containing anything like Autism and such like that is not allowed. So I feel like slowly we should progress into making Mental Health usernames inappropriate as well. Obviously these will be new rule changes, and so the slow progression into them is much needed. If usernames like such were not allowed, a ban I would think would not be implemented right away. We may ask people to change their user first, within the first month or so of this change in. But after awhile- and people should know the rules. A ban is best suggested. Why? Topics that I've seen in usernames, contain Anorexia, or Depressed. Both of those can start very harsh comments, or even arguments. Their user may be true to the person. But if they feel the need to tell someone about it, putting it in a Minecraft username is not the best idea. If they need to talk to someone, theres many phone lines, but as well as texting lines to talk to. Theres also a few groups I've seen where people can talk to others and get help and advice. There's of course Counsellors, which do wonder. Though, these are not always cheap. But for those in school, most schools do in fact have a school counsellor.
Secondly, the topic over Mental Health can be a very touchy one. I feel like appropriately discussing the topic, is perfectly fine. Its a matter of respect for everyone. I've seen in the past couple days people talking about killing themselves and stuff like that. I feel personally like joking about that sort of issue, should not be prohibited on PZ. Now, they may actually feel that way. And if so, talking on a Minecraft server about it, is not the best solution. I've previously mentioned many ways to get help. But you can also talk to parents/guardians, teachers, or any trusted adults.
Lastly, yes. I saw at some point by banning such usernames, or shutting down topics would be possibly 'shutting out those who need help'. I've stated many times, a Minecraft server is not the best place to get help. The majority of people who you're talking to, most likely do not know you very well, and if something serious was to come up. There's not any real easy way for us to get you help. The ways I suggested are much more efficient in receiving help.
This is all just my opinion, and I enjoy hearing others, as it has changed my thoughts a bit on this. Thank you xx
