There can be various reasons why someone might suddenly delete nearly all of their Instagram posts. Some possible reasons include:
Privacy concerns: The person may have become more conscious about their online presence and decided to remove personal information or images to protect their privacy.
Rebranding or change in identity: Individuals, especially influencers or public figures, may choose to delete old posts to establish a new image or rebrand themselves.
Regret or embarrassment: The person might feel regretful or embarrassed about some of their previous posts and choose to remove them to distance themselves from the content.
Clean-up or decluttering: Deleting old posts could be an attempt to tidy up their profile and maintain a more cohesive and aesthetically pleasing feed.
Moving on from the past: Deleting posts might be a way for someone to move on from a particular phase or period in their life, especially if it holds negative memories or associations.
Security concerns: In some cases, if the person believes their account has been compromised or they fear being targeted by online harassment, they may choose to delete posts as a precautionary measure.
Business strategy: Some businesses or influencers might archive or delete old posts to highlight new content or promotions, or to reset the engagement metrics on their account.
Account cleanup before deactivation: When someone is planning to deactivate or abandon their account, they may delete posts as a part of the cleanup process.
It's important to remember that everyone's motivations are unique, and without direct communication from the person in question, it's challenging to know the exact reason behind the action. Deleting posts on social media is a personal choice, and there may be various factors at play that led to that decision.
