how they found out i dont know. I deactivated all my fb accounts.
I already answered that here.
You never changed your phone number and put it open to be searched on your new facebook account that you opened 2 months later. One of the original steps is to change your phone number. You never did that.
viewtopic.php?f=20&t=35899#p134478Change your phone number, period, ok? Do it now if you have not.
Delete your two old accounts completely. Do not use them.
Abandon the email addresses that you used to make both old accounts. Do not login to them anymore.
Stay off of facebook and all other social sites for double to triple the time he looked for you, 4-6 months minimum.
During the time you are not on facebook, learn how to set all privacy settings to maximum settings, and learn how to protect yourself online. There is plenty online, including tutorial videos that can educate you on this. Google is your friend. Just type in "facebook privacy settings" and "online safety" if you are not thoroughly educated on the subjects.
When or if you ever get another social account, use all brand new email addresses to open each of them, and each with a different password. Have changed names on all of them. Something the scammer could not easily guess should he look again. Put as little information as possible on all of them.
For instance, if your name was "Robert Wagner" on the old accounts, Make it "Bob Wag." You could use a nickname that your friends know too for first, last, or entire name, like "Alexander Monday."
One thing you need to get through your skull and believe is that there is no way that you video exists anywhere anymore. He is just bothering old victims he can still find because they did not change all their details, and they let the scammer find them. He thinks he can bluff his way to another payday. You stopped his last attempt by not picking up his call.
This is the only way he can hope to get money, until you change your number. So, change it, as I have said multiple times already.
You seem to have a more serious lack of understanding and coping skills than most of the other victims here. I think that you should contact someone at home and talk to them about dealing with your increased anxiety issues over this scam. Perhaps you also have trouble dealing with other setbacks or difficulties in normal life? It might help to seek out some older person that you trust, clergy, or a professional counselor in your case, to help you to rationally deal with controlling your feelings and coping.
