The purpose of directory is to organise the internet, keep relevant sites in order , in single place to facilitate searching right sites easily. Editor needs to review a site to add it in the proper category. They need to spend times and other resources. You pay editors for their time to review the sites , and support them to spend for infrustructures. Hence IMO the directyory link is not paid BUT Yearly recurring charge is what I dont not support , it is then to me a paid link. Yes one needs to spend for resources , in that charges shoud not be the same as you charge for review. I am eagerly waiting to learn what other think.
