There is no one-size-fits-all answer to this question, as the factors that may lead to an Instagram user being shadowbanned can vary. However, some of the most common reasons for being shadowbanned on Instagram include using automated or third-party apps to like or follow other users, using bots to post comments or spam, and violating the platform's terms of service. Also, many users have noted that using too many hashtags, posting too many stories in a short period of time, or using banned hashtags can result in being shadowbanned.
