I have zero confidence in automated hatespeech blocking ever since I had comments blocked multiple times for fighting racists with reason (which is, honestly, the only way it will be eliminated, just like it worked against homophobia and interracial marriage... I wonder how long it will take before we realize that if you ban it, you martyr it, and you merely send it off to fester on some darkweb somewhere)
Homophobia has been eliminated? Since when?
How could you possibly expect to control people saying things about your blog on a remote webserver?
There is no solution that is not worse than the speech.
This is not a problem that needs solving.
It's called Aether, and it only supports text. Each node stores 6 months of all posts. Every person votes for their own moderators of communities so you can basically choose your own moderation filter that you get.
I didn't personally like the idea that it has amnesia after 6 months, but surely eventually clients would support saving your own threads to keep locally.
So you could subscribe to your own trusted adblocking/flagging list.
You're right. My point would make sense only in case of an opt-in solution.
