I saw these posts under discussion, and FWIW:
1) I saw nothing in them to suggest actual suicide.
2) I actually thought this was 80%+ a troll or group of trolls having a prank to see how frum Jews react, as some others have suspected.
Now I am not a licensed health professional. However, for over 25 years, I have had experience in the role of Rebbe, teacher, mentor, Rav etc. because of my work in Yeshivah and outreach, including manning suicide hotlines as a volunteer at times. I am also a Talmid Muvhak of R' Wolpin ZTz"l Rosh Yeshivah of Karlin Stolin, and so there are some frum young people who ask me questions all the time.
On MY, I have sometimes reached out to what appeared to be a troubled soul, by posting my support in the comments and offering my email address if they needed someone to talk to. At the same time, I found a way to gently warn them that the site was not made for the activity they wish to pursue here.
Usually they do not contact me.
Sometimes over the past 3+ years, some of them did reach out. I remember for instance speaking with a struggling ger tzedek candidate, a legitimate bochur who really needed tefillin, and a guy who was so depressed because his marriage was falling apart etc. as well as others.
When they first talk to me, i explain that I am not their Rav or doctor etc. so if they have real medical issues or serious practical Halachic questions, they should ask their professional. If they don't have one, I offer to help them find one. If they do not wish to expose themselves to an expert, I listen to their issue and act as go-between with a posek or doctor so they are not held back by shame etc.
Usually, however, they just want to talk to someone who can listen and they won't need to see in shul after their confessional :) Most Halachic questions are pretty simple and B"H I can answer them.
So what should we do about future posts?
1) We should definitely let the mods and community continue to do what is needed to keep the site under control including limiting inappropriate posts.
2) When that is done, someone needs to post a comment offering real heartfelt concern over their issue while apologizing about not being able to have this forum act as the outlet they need.
3) We can post for them a good hotline # and/or website to someone/place that we honestly think can help.
4) Any one of us who is brave enough can offer an email and time to listen to them vent. Taking it private and safe (because your email is private etc) and maybe doing a mitzvah.
5) Personal time permitting you can always contact me at [email protected] and ask me to give them my email and an invitation to talk it out.
But if a troll is really identified or a 100% harasser etc., then the best thing is the mods clean it up and no one talks to them. :)
Just my 2 cents.
TY, David
