Features are intermittent, it seems. I can browse the app, but posting and commenting just doesn't work.
I am curious what this 'cleaning crew' is. I suspect they are terrified of the spread of news of trials and the like spreading through their platform. Many real people follow each other through FB. A facebook page can have a bit more pull than people realize.
On the other hand, it could be that they are pulling app features and support. Ghidra is a public tool, now, and there will be dedicated people looking to crack the program to peek under the hood. Ghidra basically breaks the program code back into "source code" - while not the original source, you can trace the relationship of variables and equations, check what strings a program is looking for, etc. That is going to be a nightmare for FB.
We'll see in a bit.
I left messages in a bottle for people I care about in the event the site is effectively "read only" - and even if not, I know that the one in particular I care about has been peeking in on things… And probably knows more than I initially thought, due to a comment I got from a throw-away account out of the blue.
