Yes, I think:
The spammers don't often implement their own TCP/IP stacks, and
therefore if their code doesn't check that it's taking an inordinately
long time to write anything to the TCP socket, they'll be stuck.
Wasn't there an article on slashdot a while back where a company had
created a similar throttling system using asynchronous perl? I believe
they claimed it worked well at stopping spam.
However, if technique this isn't wide-spread, which it's not, spammers
can effectively ignore it.
