Will SETI taste like spam?

You may be aware of the SETI project - Search for Extraterrestrial Intelligence. A number of efforts have been organized to detect signs of intelligent extraterrestrial life. The general approach of most SETI efforts is to survey the sky for for evidence of transmissions from a civilization on some distant planet. A certain form, known as Active SETI or METI (Messages to Extraterrestrial Intelligence) consists of sending signals into space in the hope that they will be detected by an extraterrestrial intelligence. Discussions of this approach consider that a response may be altruistic, benign, or malevolent.

Let's consider this possibility. Extraterrestrial life detects our signals and responds. If they react like us humans do, pretty soon we will be overrun with extraterrestrial messages offering various devices for penis enlargement. We will receive requests to supply personal banking information so that the First Galactic Bank of Arcturus can verify our records. We will receive requests soliciting our assistance in moving large amounts of money trapped in an account held by a wealthy alien in the Sirius sector.
