What to do if you are a victim of crime
If you are a victim of cyber crime, you must first inform your family and friends without any fear.
If the family or friend is scared without telling anyone, the first objective of the criminal is successful. Its first purpose is to separate you from family and friends so that you are mentally weak and cannot take action against it.
If the account is hacked, first warn your friends, so that your friends can be alert if any crime is committed with your account and try to recover the account.
If you are a victim of blackmail through personal photos, videos, audios, photoshopped pornographic images or if you go viral online or if you are in danger of it, you must seek legal help. If you need to do GD, you must do it.
