What do you think is the proportion of people who post about killing themselves and actually to people who post about it but never do it? 3:1? 2:3? 1:9?
I'm sure we've all seen lots of people who make posts about how they're gonna do it tomorrow and why their life is so meaningless, etc. etc., but then again, maybe they just like seeing people trying to discourage them from doing it and like the idea of believing that there might be something that somebody might be able to tell them that should solve all of their problems. Or maybe they just like getting told "Yeah, go stream it, faggot".
