Just add the email addresses of spammers.
I got this idea as someone has been annoying
me with crap emails asking me to join Jahoo
or whatever sites. To retaliate them, to let
them get spams, added those emails below.
notwo20042005 _@_ yahoo _._ com;
soelay206583 at gmail _dot_ com;
soelay206583 _@_ gmail _._ com;
notwo20042005 is the yahoo email account
while soelay206583 is a google mail account
Other spammers' crawlers will do their jobs.
I hope their email account extraction algo are
good enough.
