How to prevent other users from using your email address to find you using the search section on Facebook?

When someone add your email as a secondary email, facebook sent you a confirmation email to varify. If you varified then it is used as a secondary email. If you did not then, no worry.

Ask him to remove your email from secondary email on his facebook.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
