If you’ve ever had a suspicion that someone is using your Facebook account without your permission, there are a few things you can do to find out for sure. First, try logging out of your account and then logging back in. If the person who is using your account is still logged in, they will have to log out as well. If that doesn’t work, you can try contacting Facebook support. They will be able to help you determine if the account is fake or not. Additionally, they can help you remove any posts or messages that were made with the fake account. ..
