Back in my home country I doubt that anyone I know is on this site. We have this firewall that blocks everything (including google, youtube, etc) and everyone has to find their way around this, get vpn or smth. That alone decreases the chance of them finding this site. I didn't know anything about this site until this summer, and for me it was already 2 years out of that shithole (and here I am in another shithole that just isp-blocked this site today. How ironic lol). Another thing is this forum uses English and people generally find it harder to communicate in their second language if they're ever able to get hold of one. Again I'm very glad that for me it doesn't seem much of a problem. I don't know what to do without SaSu tbh.
For the ppl I'm in contact with now I don't know for sure and I don't think I'll ever know. There's this whole chain of suspicion thing going on irl. You don't know how people will react if they find out that you're suicidal, and they don't know how you'll react either. In the end everyone just hide themselves, put on masks and pretend to be normal. It's interesting though to think about the possibility that someone I meet on a daily basis is actually here as well lol.
