I’m plagued with this sort of ‘polite’ spam – getting tons of them a day. I’ve contacted the folk at wp-spamfree via the contact form on their site several times – not had a reply. I’ve sent them a couple of message via twitter – no repsponse there either. Getting the feeling that they don’t give a s**t. So now looking for another plugin to combat spam as wp-spamfree no longer works.
