I feel like, even on non-anonymous platforms, the onus is on a prosecutor to figure it out. Moderators should do their best effort but it is an impossible task. Would you hold a mail carrier liable for what they deliver?
The mail carrier is more like the internet, or an isp. They transport the message. And as common carriers they are not responsible for the content.
Amazon is more like a public bar, that posts the postcards on it's giant message board for all to see.
And it would be expected of the bar to be somewhat responsible for what they choose to hang up or not.
That’s an interesting analogy. I used graffiti in another post trying to put some context to the problem.
In a small community like a bar, it’s reasonable to expect the owner to take down offensive content (for their reputation if nothing else).
In a bar with millions of people, that’s definitely harder. Amazon can afford it, but on the other side: should volunteer fediverse instance admins be required to review every post?
Graffiti is not a great analogy because it's not what your property is made for. If you had a wall on your property that you made publicly accessible specifically for graffiti, then you may be responsible for what you allow to stay up on it. Otherwise, it's just someone vandalising your property.
Maybe graffiti? I’m not really sure what my legal obligations are if someone were to put a public-facing obscenity on my property. I’d clean it up, but it would be a lot harder if it happened thousands of times a day.
