Shit like this is why, when I have to ban someone or remove a comment or a post, I always make a public comment.
There should be no ambiguity over it.
This Community is to showcase a screenshot of the Last Post or Comment you made before a platform or community banned you. We are eager to see what got you banned from Reddit, a particular subreddit, Twitter, a Mastodon instance, or even a Lemmy community! We understand that some bans are legitimate (for example, posting spam or being a dick). This community is to showcase mod abuse and censorship.

Shadow banning is one of the most toxic moderation practices on any platform. If a site or community has a set of guidelines then there is no reason it shouldn't be enforced openly.
Having to give a justification or even just a public notification of a mod action makes a moderator have to think a bit more about why they're taking an action and how it might effect the community.
People who run a privately owned forum are entitled to run it however they wish, but shadowbanning eliminates any chance for the members of a community to really understand how the community is truly being run, which robs them of their ability to make informed decisions about their own participation in that community.
