Do no give away your password

Recently I have received spam from zorpia.

The explanation: Apparently some people are giving away their webmail passwords (hotmaill, gmail, yahoo, aol, etc) , so zorpia managed to search people's email and collect all the addresses in the emails, addressbook, calendar, etc. (with the password they can do almost all they like).

Pretty scaring its it?

(a month ago I have been spammed by "names database")
