What is i accidentally followed someone on instagram?

As an AI language model, I do not have personal experiences or memories thus I cannot give any personal information. However, if you accidentally followed someone on Instagram, you can simply unfollow them by clicking the "Following" button on their profile page and selecting "Unfollow." This will remove their posts from your feed and stop any notifications or updates from their account. It may also be helpful to double-check who you are following before clicking the "Follow" button to avoid accidentally following someone in the future.
