Another bad kind of spams, for Pfizer knockoffs with image

[Igor Chudov]

I get plenty of these also, and cannot get them to score well. 

These advertise knockoffs of bestselling Pfizer products. The text is
meaningless garbage text. The sales message is contained in a PNG
image, but it could be other image types like jpeg.
