I didn't know about the BBC thing, that's a pretty big deal for the fediverse. A question though, in the linked BBC article, it seems like they're heavily relying on moderation to come from the home instance of anyone who posts a reply to a BBC post. If a self hosted troll server decides to start aggressively spamming these media accounts, or posts illegal material as replies to their posts, what could a media organization do to stop it? Is there any protection against say a wide network of troll servers working together?
Traditional social media at least theoretically has a better ability to shut this sort of activity down because they can see the whole picture of user activity and use algorithms to discover and ban bots. I worry that decentralization itself will become an attack vector for malicious activity.
