You didn't reply so Google says
"Shadow banning (or stealth banning) is the covert practice used by social media platforms and online forums to restrict or hide a user's content from others—making it invisible to the public—without notifying the user. The user can still post, but their engagement (likes, comments, reach) drops significantly.
Key Aspects of Shadow Banning:
Invisible Penalties: The user usually does not know they have been restricted, as their content remains visible to themselves, creating the illusion of normal activity.
Purpose: It is used to curb spammers, trolls, bots, or users violating community guidelines without prompting them to create a new account immediately.
Common Signs: A sudden, significant drop in reach, engagement, or followers; posts not appearing in hashtags, search results, or the Explore page.
Platform Specifics: Platforms like Instagram and TikTok may limit content from being recommended to non-followers if it violates community guidelines. On X (formerly Twitter), it can be triggered by "low tweet credit" or violating sensitivity policies.
Duration: Shadow bans are not usually permanent and can last from a few days to several weeks.
Common reasons for being shadow-banned include using banned hashtags, posting spam, aggressive automation, or posting controversial content that violates platform rules. "
