For me this is the closest reddit alternative i know of. Sure lemmy isint as big as reddit and reddit has far more tech issues, But im new here so i cant really say much.
Do you prefer lemmy or reddit? are there any other social media i should try? please briefly explain your thoughts and ideals.
Maybe this is what you may like? This was from the Piefed settings
It appears there is a setting where you can only get private messages from your instance, or trusted instances if that is appealing
