Recently, my company had to kick someone over a very real issue as well as contacted GMs about this issue.
This person's psychological state was not...good. They kept talking about their issues with suicide and every little thing we did as our usual joking around they took offense to and started threatening to commit suicide over us joking around with each other. And then when we all talked to her about this, she threatened to commit suicide if we kicked her out (and implied that she would when we did).
In other MMOs like WoW, Guild leaders can contact GMs over issues of suicide where in which they have substantial proof that this is a concern (which we have logs upon logs of), they can track the person's IP address and call the police. Right now, none of us know what happened to this person and despite we asked her to leave for her safety (because clearly our FC was not a fit for them) and the safety and comfort of our members and people who we are associated with (who them also brought into this mess)....
Myself (the leader) and multiple officers contacted GMs in game out of concern and got a response that was like "You can't contact on behalf of another player and wait until this person logs in again."
So we're kind of stuck and many of us are feeling guilty.
I think that SE needs to have some sort of procedure for these kinds of reports. MMOs are played by all sorts of people, including people with psychological problems that shouldn't (and by law can't) fall on the responsibility of FC leaders to solve--which this person expected us to do. We can't call the police for this person as we don't know where she lives...If we have a legit report like this we should be able to report it and I am disappointed in SE for potentially ignoring a report like this where someone's life is literally in danger.
I am not sure if anyone else has been in this situation in their company or in other games...Not sure what else I or the other officers can do.
