How To Fix Instagram Shadow Ban [Tested and Working]

Ways to remove the Instagram Shadowban:

Backoff from posting for a couple of days - Some people have stopped using Instagram for over 3 days (or more). Their ban was lifted after that.

Delete all hashtags from your recent posts - This trick worked well for a lot of people and it seems to be the fastest way to remove the Instagram shadowban. 
 
People have also reported that not using the same hashtags over and over again helps. It signals to Instagram you are an active user and not a bot.

Put your hashtags in the caption (not in the comments) - People reported that when they put their hashtags in the comments, their post was shadowbanned after 1 – 2 hours. Stop doing this for future posts and go back to your recent posts and fix them up.

Don’t use too many hashtags - Remove hashtags from old posts and make sure to use less than 30 hashtags

Contact Instagram - Get in touch with Instagram. Some people got unbanned reporting the problem to Instagram.

There are different ways to get in touch with Instagram: Through their website, the app, Facebook page or email them directly (support@instagram.com). Tell them: “I am not being shown in the hashtags I’ve used for my post”. Do not say you have been “shadowbanned”.

Do not switch to a business profile - Many users have experienced a loss of engagement after switching to a business profile.
