So, a guy named Randahl needed help translating a Danish phrase to English, and tagged another Mastodon user to ask. Four months later, someone on Bluesky read the post - which showed the image of the user he tagged instead of the link he needed help with - and was offended that he'd posted the user's profile to Bluesky. Which he hadn't done intentionally... it was an error in the way the bridge to Bluesky parsed the links. It blew up. He has since apologized, but many folks have blocked him.
