1. Excessive Engagement on Old Social Media Posts

What It Is: Someone repeatedly likes, comments on, or interacts with your older posts from weeks or months ago.
What Sources Say: According to psychology research, likes or comments on old posts can indicate extensive profile browsing. This behavior suggests someone has been scrolling through your entire social media history, often going back months or years to access older content.
Why It Matters: While occasional interactions are normal, a pattern of engagement with old posts may indicate obsessive monitoring of your online presence. This behavior often escalates to other forms of digital tracking.
