Maybe I'm missing something or I have some lack of perspective going on, but I personally really don't think that this is a huge catastrophe. There's more to SS than just methods, as @Callie Arcale and a few others already mentioned, but even then, there is already a plethora of information here and can be found upon simply using the search function. IMO, just based on my experience of having been here for 3+ years and having looked at A LOT of threads, all this is really preventing is people asking and answering the same questions over and over again.
It's fucked right up what these anti-choicers are doing, though, in any case – they ultimately don't have a very strong case, so it seems that they try to cover that up by largely using scare tactics, doxxing and intimidation against suicidal and otherwise vulnerable people – the very people they claim to be advocating for; what a joke – who are just trying to find a sense of community, belonging and understanding on a website because they couldn't find that in the "real" world that had so badly failed them. I swear to God, these anti-choicers don't even live on this planet.
Anyway, I know that this wasn't a decision made lightly by @RainAndSadness and the rest of the staff, but ultimately it's about taking the necessary measures to get through this rough patch (of which there have been many, and we've gotten through all of them) and keep SS up and running for us, which I can only imagine is not always easy, so I respect and support this decision.
