I think if someone is posting about suicidal thoughts, I hope the ban also comes with helping that person find resources to get help. From a mental health perspective you dont want a posting that might also trigger other people who are thinking about it or may have attempted it already or had a loved one who went through with it etc...Trolls might also start encouraging it just to be dicks and his feelings of death start to escalate. That may make the site liable in some way. I feel for him and I hope he knows God loves him and there are people that care. Sometimes you dont feel it at the moment but everyone is worthy of having a good life. This site like any site, if they really cared about people that visit, dont just ban someone and leave them hanging. Help the person find resources, for some, posting their feelings might be the only outlet they have.
