A 404 just means it hasn't been added to the instance yet, I just added it now by doing https://fedia.io/search?q=%21asktransgender%40lemmy.blahaj.zone (though it'll need a local subscriber to get updates)
On my list is to try to make it clearer on how to add remote magazines. In regards to whether that message means it was a local or remote delete for remote content... From my experience the only time I've seen deletes federate is when it's a remote instance A moderator acting on a remote instance A user post. Meaning if a remote Instance A moderator acts on a remote instance B user, it does not federate.
OsaErisXero mentioned the issue for fixing that in the thread, but for some reason my reply didn't federate, so that's why I'm posting from your local instance
just wanted to post on the incredibly low chance debounced ever sees this that I hope he's ok and wish him well with whatever happened
