Ah, Bluesky, my sweet summer child.
You're going to enforce your "rules against harassment and toxic content". And then you'll discover that it's the same set of people doing the toxic shit. And those toxic people are connected to really powerful people from a specific political party.
And suddenly you'll be getting calls from really wealthy fascists asking why you're enforcing this liberal bias by squashing conservative speech...
It's so predictable I can't even. There is no neutral position. If you clamp down on all the hate speech and toxic shit, you will clamp down disproportionately on a specific demographic who will throw a (potentially violent) temper tantrum.
The thing is, Bluesky is fundamentally capitalist. They need money and all the money is with the fascists these days. If they clamp down on toxic fascists, they will clamp down on wealthy fascists and their money will dry up. This won't last.
