Lmfao you just came in and downvoted me at the same time as I finally conceded and accepted having a little edit mark on my comment.
I couldn't think of a better way to phrase it when I wrote the comment, but yes, "angry" would be an excessive description of your comment. Not quite so excessive with your latest comment, though :P
Yes, if it was removed by a mod. If it was deleted by the creator, then no.
Also strictly speaking maybe no if the admin of the user's instance did some special fuckery. Every post or comment is hosted first on the user's instance, then federated, so if the user's instance is running altered lemmy code then it could do all sorts of funky shit.
Edit: @mizu6079@lemmy.world is still around, so maybe they'll come and answer. That should have sent them a mention, the instance agnostic link for them is /u/mizu6079@lemmy.world (if your app can handle those, it will be a link on the website). Seems like they deleted all their comments.
Edit2: The original post still exists for me: https://lemm.ee/post/241183. You'll have to browse their profile using the instance agnostic link to see if it's on your instance.
Edit3: I see nothing on the lemmy.world instance, looks like they wiped their account entirely. Yet their posts do seem to exist still on some other instances.
