If you've noticed a decrease in your Twitter interactions or suspect that your content is being hidden or reduced in visibility, it could be a shadow ban. The good news is, there are some easy ways to check if you're shadowbanned on twitter.
Start by logging out of your account, and then opening an incognito tab on your browser. Navigate to the discover Twitter page and search for your name in the search box. If you can't see your tweets on the results, this is a sign that you are being shadowbanned by X.
Alternatively, you can use a third-party service that can perform a shadowban test for you. These services require you to provide your account information, so make sure the service is trustworthy before providing any details. Once you've entered your username, the service will check whether Twitter is hiding your replies on other users' posts. This is known as the ghost or thread ban and is used to limit the reach of content that violates Twitter's rules.
Another way to check if you're being shadowbanned is to review your profile and delete any posts that violate Twitter's rules. This will help prevent future issues. However, it can take a long time to manually find and remove every post that breaks the rules. You can also try using a tool like TweetEraser that automatically deletes any tweet that breaks Twitter's rules. If none of these solutions work, you may have to contact Twitter's customer support and explain your situation.
