Discovered by Flit on a Fediverse instance, akkoma.flitpix.net, Bluesky sends media to an AI service known as The Hive, a service used to search, generate and moderate content. It is baked into their protocol, and NOT part of the web or mobile apps. That's why it is why has similar content warning features to Mastodon, and is friendly to NSFW content.

PLEASE, PLEASE take Bluesky with a grain of salt.
