No, there's no official way for someone to know if you're stalking them on Instagram. The app doesn't have a feature that alerts users about who's been viewing their profile.
However, there are a few indirect ways someone might suspect you're checking their profile:
- Increased Engagement: If you suddenly start liking and commenting on their posts more often, they might notice.
- Direct Messages: If you send them direct messages, they'll obviously know it's you.
- Mutual Friends: If you and the person you're "stalking" have mutual friends, those friends might notice you're interacting with their posts and tell them.
- Stories Viewing: Instagram does show the number of people who have viewed their story, but it doesn't reveal who those people are.
Ultimately, whether or not someone suspects you're stalking them on Instagram depends on their awareness and how closely they pay attention to their account activity.
