Bloomberg Binary Trades. Never stop calling - en after being told you have no interest in binary scams - they call continuously through the day and into the night. They never ask for you by name, but claim they cannot stop calling you unless you give them your name. Which is probably another way to try to harvest more information to use/abuse or sell.
