Quite the opposite of being shadowbanned in fact. Unless an instance is doing something custom, you can peruse an instance's modlog: https://lemmy.ml/modlog

Using lemmy.ml as example not because I'm painting the entire instance with the same brush, just came to mind because I had a comment removed for being "reactionary".

Can't recall what I said, perhaps there is a time limit on how far back the mod log is accessible.
