I've said it before but this is a good time to say it again: Lemmy can be more authoritarian than even Reddit.
Yes there is a modlog, but no notifications, no modmail, no ability to even know who did the moderation other than that it was done by a "mod" - Reddit at least told us that we were banned?!?! and allowed for an appeal process - all of which makes total sense when you consider the authoritarian nature of the devs, who are well-known for site-wide banning upon saying something that they disagree with (even simple facts).
I am much happier on PieFed, which offers numerous options for democratization of moderation - e.g. you can place icons next to users names, or have that done automatically based on rules, thereby increasing the set of options from the binary "remove post or ban" vs. "do nothing, leave it alone for everyone to see" to allow you to decide what to do based on those. Like there are keyword filters in place (beyond simply "All" vs. "None", also offering "Some", if you wanted e.g. some Trump or Musk content but less than the currently tsunami of it!), thereby allowing a mod to leave a post up and allow the community members to individually tailor the content to suit their tastes. Like for a <2 week account, I may respond differently; or for someone who receives 10x more downvotes than upvotes, I may choose not to respond at all rather than waste time on such sea-lioning tactics.
Lemmy was made by the people who got banned from Reddit for being too toxic. We are using their tools, made for and by authoritarians, unless we build and use better (like Mbin and now PieFed).
This specific thing - about notifications - may change (though it has not in the 2 years I moved here from Reddit... only getting worse in fact, as the modlog used to say the name of the mod but now it simply says "mod"), but the overall trend looks like it will not.
