I don't see a problem with being public and having limiting rules - it's perfectly fine for women or minority groups to have their own spaces - but never before have I seen such an odd approach to moderating. I too tumbled on one of their threads from ALL and it felt like at least third of the comments there was responded with, paraphrasing, "please never post again". If every discussion reaching ALL gets like that, I'd imagine it would be easier to figure out some other solution, since it takes such insane amount of effort to go through so many comments and probably profiles and posting history to know who to reply that to, from moderating perspective. Or are they just saying that to everyone? Or everyone not subbed?? I doubt that many people getting answered with "please never post again" would want to join even if they did qualify...
It's just... I don't understand the logistics of all that
It's a stress reaction instinct thing if someone reading this didn't know already. Something like "they're not going to survive anyway, better use the resources myself to be able to escape and make more". Many mammals kill their own young when stressed, I theoretize it could be somewhat behind post-partum depression as well since that can create strong feelings about how you have to kill your baby
