If someone has blocked you on Instagram, there are a few signs that can indicate this:
1. Profile not found: When you search for the person's username or try to access their profile, you may receive a message saying "No posts yet" or "User not found." This indicates that their profile is either deactivated, deleted, or you have been blocked.
2. Disappearing comments and likes: If you previously had interactions with the person on Instagram, such as leaving comments or liking their posts, and suddenly those interactions disappear, it could be an indication that you have been blocked. Your previous comments and likes may no longer be visible on their posts.
3. Unable to send messages or view stories: If you try to send a direct message to the person who may have blocked you, the message will not be delivered. Additionally, you won't be able to see their stories or view their live videos if you have been blocked.
4. Mutual friends' posts and comments: If you have mutual friends with the person who potentially blocked you, and you notice that their posts or comments no longer appear on your feed or are no longer visible to you, it could be a sign that the person has blocked you.
It's important to note that these signs are not definitive proof of being blocked, as there could be other reasons for these actions. To confirm whether you have been blocked, you can try using a different Instagram account or ask a mutual friend to check if the person's profile is visible to them.
