Was it mods or self deleted?
Lemmy features modlogs, so you can just go check. It’s in the sidebar. Instances also have modlogs, so if admins did it, you can check that too.
Also I didn’t see the post, but it sounds like it would be against the community rules.
“Do you compress files, if so why?” would be a discussion question
“Help me fix my file compression problem” would not be

I think the OP of that post stated they’re the ones who edited the title to that before the mods deleted it, but I can barely understand what they’re saying in their comment.
You’d have to ask that guy, I suppose. He posted it to two different communities, and neither community’s modlog show that post being deleted by a mod, so they definitely removed it themself.

That message is only in lemmy.ml, but the same post was made in lemmy.world and there’s no message like that at all. It’s possible one was deleted and the other was removed, but it’s also possible that that is a different post entirely. You’d need to ask the poster.

Huh. Fair enough. Still doesn’t explain the lemmy.world one, but they might have had one deleted and deleted the other one as a response.
