You can check for any Twitter account that you are allowed to see how many of their last followers have a twopscore lower than 3, which is often an indication for fake and/or inactive accounts. If you check your own account you can check up to 500 of your last followers, and block them immediately if you want. If you have a huge problem with accounts you would like to block, contact us and we can help you to manage your followers, and block undesirable followers for you.
