Got this exact same one. I just got “hello” but when I tried to just delete the message, I get this error saying I can’t edit the message (pic below). Using lemmy.world. Maybe it’s a bug or something? I’ll have to check the settings because Id rather just never recieve dms ever. At the very least, be able to just delete them.

First DM I ever got on lemmy.

My wife loves it and I hate it for the exact same reasons.
