Whether I can control the visibility of it is beside the point, hiding it doesn't mean you're not sharing a platform with it and with zaps and such the likelihood to being a single jump away from contributing to it is high.

It's important to note that most people aren't affected by moderation on other platforms either, so while there's a benefit to a far-right extremist who has been banned from twitter coming over here, there is no such similar benefit to a normal person.

If I see enough abhorrent content and have to hide it, I'm just going to exit the platform. Most normal people will do the same, rather than constantly chasing everything with a filter, and so the ratio of abhorrent content will only increase. This happens to all zero censorship platforms in the end.

Out in the street there are laws, so it's not a particularly strong analogy.

I haven't had a chance to look yet, but I assume that when I mute someone they can continue to tag me in things they post, is that correct? Meaning that people who are targeted with hateful abuse will carry that around with them with no recourse.
