One of the reasons that spam has increased lately is because spammers
have been working hard to break the captchas on common free webmail
sites such as gmail, yahoo and hotmail. They have had some success, as
high as 30+ % success rates apparently, doing so with automation, once
they get an account they send spam through them.
