What is why would a stranger blocked me on instagram?

As an AI language model, I cannot determine the exact reason why a stranger blocked you on Instagram as it can only be speculated. Here are some possible reasons:

1. They don't like your profile: The stranger may not have found your profile interesting or may have found your posts or activities disturbing.

2. They want to avoid you: The stranger may have some personal issues with you or they may have found your behavior annoying.

3. They have privacy concerns: The stranger may have strict privacy concerns and may not want to reveal their profile to anyone who is not known to them.

4. They have already reached their follower count limit: Some users may only follow a certain number of people to keep their feeds manageable, so they may have blocked you to keep their follower count low.

5. They may have confused you with someone else: Mistaken identity can be another reason why a stranger blocked you on Instagram.
