What if the instance owner blocked your IP (or even a MAC address if they could) from connecting to the server? That would effectively “shadow” ban a user in the sense nobody else would know they got banned (nothing in the modlog either). The user might not know they were banned, and just assume there’s an issue.
Every action is public in the mod log so I don’t think shadow bans are possible although you might not know to check the mod logs in the moment
