The big question with internet publishing forums today is that most of them want the immunity of a disinterested party, while still taking great liberties at screening, moderating, and controlling content that is published on their platforms. It appears as though Hive makes it a point to stay out of people's way and let the ledger speak for itself. But I do know that copyright infringement and plagiarism are frowned upon, as these would bring a lot of unwanted legal attention to the platform. As would allowing indecent material regarding children, for instance.
Section 230 of the Communications Decency Act says that "No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider."
The problem is, they are allowed to moderate, screen, and pull content from the public view all they want, which makes them an interested publisher in my opinion. But they are protected against liability for the attacks in 2019 linked to Hamas, where those attacks were orchestrated on FB and FB was not held liable in any way.
Congress on both sides of the aisle think Big Internet has too much reach and not enough liability. And Australia seems to be handling those guys a LOT better than we are in the US.
