Fighting Spam!

I have got this clear email scam through 3 of my emails, addressing me by the same name I used when registered those 3 free emails accounts. This proves that this email I have received is 100% spam. I have never signed or have an account with this very (stupid) bank, if there's such bank by this name.

I received this email daily and didn't want to delete or block it using the two blocking systems I have, during that "scam observation period" which I give actually to every kind of spam I am receiving, to track its sources. The scam always goes this way:
