I plagued by a number of junk artists who take a lot of trouble to convince me that directories are just a waste of everyones time. They flood them all with inappropriate submissions irrespective if I switch Captua on, request a reciprocal or make them paid only. Why do they do it? Its a waste of everyones time.
I assume they offer a submission service and charge their clients for a listing of the directories that are not going to approve their links.
