As a similar but more extreme example.  2 years ago we shut down several 
old domains.  They were receiving 20,000 spams/day at the time, 
virtually zero legit email.
A few months ago I turned them back on.  800,000 spams/day after 18+ 
months of 100% undeliverable.  40-fold increase.  Ouch!
[And of course several semi-legitimate bulk mailers who don't check 
bounces either.]
