I'm sorry to hear that you're facing this issue with a poser on Facebook. Dealing with posers and impersonators can be frustrating, but there are steps you can take to address the situation. Here are some suggestions:
1. Report the account: You mentioned that you already tried reporting the account, but if you haven't received any response from Facebook, you can try reporting it again. Make sure to provide detailed information about the situation and explain how the impersonator is affecting your image.
2. Gather evidence: Collect evidence to support your claim. Take screenshots of the impersonator's account, including any posts or messages that are damaging your image. This evidence can be helpful when reporting the account to Facebook.
3. Inform your friends and family: Let your friends and family know about the poser's account so they don't get deceived by the impersonator. Ask them to report the account as well, which can increase the chances of Facebook taking action.
4. Reach out to Facebook Help Center: Visit the Facebook Help Center and look for options to contact their support team directly. Explain your situation and provide all the evidence you have gathered. Facebook may investigate the account and take appropriate action.
5. Protect your own account: Ensure that your own Facebook account is secure. Change your password to something strong and unique, enable two-factor authentication, and review your privacy settings to limit what personal information is visible to others.
Remember, it can take some time for Facebook to respond to reports, so be patient. In the meantime, continue to gather evidence and document any further instances of impersonation.
