I wish to every single person on that website the most horrific, painful, gruesome, brutal and torturous end that will make the most powerful people shit their pants.
But like all things in life, the authorities will probably do nothing about it because they either secretly support it and probably live in that site in secret, or they just don't care about what happens to everyone else so soon as they still live comfortably and get paid. Even if this site does get what it deserves in the end, those people won't and will just migrate to the next big thing. Like Twitter.
I hate this as much as you and everyone else does, but unless those people are executed or imprisoned for life, this kind of shit will never end, it will grow and grow until we live in a dystopia that's run by these very unnatural freaks who hide behind their screens and keyboards.
