They vary all over the map.  Betterly talked about making 5 $300 sales 
from a million spams.  One of the reported "takes" from the IRAQ playing 
cards spammer was on the order of $18 for several million spams.

Note that MSN's DAV system has had a 100/day limit for a long while. 
They appeared to implement the human test a week or so ago. (volume 
dropped off from about 20,000 per day to a handful).

A little bird talked about DAV abusers registering thousands of accounts 
at a time.
