Sirius clueless?

In GoF, I don't understand how Sirius would not know what Karkaroof was 
showing Snape (pages 531-532).
If Sirius was battling Death Eaters, surely he or his other fighters would 
have noticed the mark on the Death Eaters' arms, 
OR
when the Death Eaters were put in Azkaban, the authorities must write down 
more than name and address.  Any place of incarceration writes down all body 
making for possible identification.
V was not vaporized when some of his followers were arrested.  Didn't anyone 
notice the arm markings?
