If someone is genuinely interested in your profile, you can usually tell from a few small signs — like consistently viewing your stories, liking older posts, or engaging with your content more than just occasionally. But honestly, Instagram doesn’t give us much transparency, so it can be hard to know for sure.
What I’ve found helpful is using tools like DolphinRadar (
https://www.dolphinradar.com/). It lets you check someone’s recent follows, and you can also view or download their IG posts anonymously. Everything is completely private, so you can see their activity without them knowing. It’s actually pretty useful if you’re trying to figure out whether someone is genuinely paying attention to you or just casually browsing.
