@lemmyworld oh fun! I can post to Lemmy.world from a random Mastodon account without having an account on lemmy.world. Despite the fact that it appears they mandate I have an account to comment (and presumably post). Let's see if this post reply works...
@sass@lemmyworld@infosecpub@[email protected] omg now I'm real confused 🤣. I can post to Lemmy instances from mastodon and randomly @ other Lemmy instances which will in turn create posts there too. @'ing my Mastodon handle works and then I can reply to that post.
It looks like a Lemmy user @joyjoy had no problem replying to my Mastodon-originated post so it would seem that strange issue may be isolated to infosec.pub.
