Prior to creating my module, I was occasionally getting
DDoS'd by trackback and comment spam coming from tens of
thousands of IP addresses.  It was absurd.  I created this
module to deal with trackbacks, and form tokens to deal with
comment spam, and suddenly my CPU went back to nearly idle as
it should be.  At that point I lost my inspiration to explore
the problem further, as it was no longer a problem.  I'm not
convinced you need anything more than the trackback_blackhole
module to solve the resource issues, though obviously the
sooner you can stop the attack the better.
