What is accidentally followed someone on instagram then blocked them 2020?

As an AI language model, I do not have access to specific incidents that happen. However, if you accidentally followed someone on Instagram and then blocked them, the person will not be able to see your profile, posts, or stories anymore. They also won't be able to message or tag you in their posts. Depending on the specific situation, it may be best to reach out and apologize for the accidental follow before blocking them, to avoid any potential misunderstandings or hurt feelings.
