I also found a thread on here where some guy from blowsearch pretty much defended the quality of their program. The thread abrubtly ended in May of 2005 and their was no update to those in the thread who were testing blowsearch.
My rep just called. I told him to just refund my money because the feedback from webmasterworld was pretty negative...Plus, this "Click Defender" thing is not even in use, and their positive press stopped back in July and there has been nothing since.
But seriously...researching webmaster world played a VERY heavy role in my decision to cancel.
