RoL is well past the point of any of us being able to help and it's absolutely not fair to put that kind of responsibility on any individual or community. It's unfortunate that kindhearted people will be easily manipulated by these kinds of tragic stories. It IS tragic, but no one will benefit if you don't put your personal safety and wellbeing first, and also that of the community.
We can have other discussions about toxicity, bullying, the harms that do go on in this community. But no amount of kindness or goodwill will cure schizophrenia. RoL needs a real life intervention and unless people are working towards that, then these discussions are fruitless and only serve to make her mental state worse through rewarding her behavior.
Edit: Also, for people who have just found out about this for the first time, it's very important to understand that this has been going on for so long. So many people TRIED for YEARS to help and got burnt out doing so because none of us can treat severe mental illness through the Internet. This didn't just come out of nowhere. Eventually people remove themselves from the situation because they realize that they are sacrificing themselves pointlessly over and over, and they should not be blamed for that.
