How do you block email addresses in Yahoo mail?

You would use the blocked address list. Hover over the far right gear icon? In Yahoo mail and then click "settings".

Then click "Blocked Addresses" in left column.

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.
