Honestly I'm very skeptical of any accusation of harassment online, seeing as you can just block people. Maybe I've never experienced it and don't know. When I ehar the word harassment I think of showing up to someone's workplace, home, things where you can't avoid them. Sending them messages that can be blocked, I'm not so sure. But that's a tangent to the topic of our discussion.
Publishing someone's address and telling people to go to their home and harass or harm them is direct incitement. This is absolutely punishable, because it's more than speech, it's conspiring to commit real world action, as you said. I'm curious, if that's the sort of thing they do, has anyone been criminally charged or convicted for such behavior? I mean that genuinely, I'm trying to learn about all this kiwifarms stuff as much as I can.
But this is just business - that is all this is, not a right, not a government, not a monopoly, not even an essential service. CF wants to cast themselves as some principled and righteous defender, but they are just a business that was finding it profitable to provide services to another business, and now they don’t.
Like harassing someone? Or like publishing someones personal information to attempt to have them harassed or hurt? Sounds like speech is a “real world action” that has observable effects… and oh, it looks like the courts may even have considered this…
