Until recently we were allowing submitters access at no cost but found it was simply too time consuming, server heavy and detrimental to our business and our SafeList owners to continue doing this so we have no alternative but to charge a fee in anticipation of a controlled environment making it beneficial for the SafeList and Submitter owners together. 

To ensure quality of service for our Safelist's it costs to  maintain and monitor the server at all times.  By running a SafeList Submitter service utilizing our Safelist's you will be using those expensive resources as well.  You will be making money from our efforts along with our SafeList owners. You will be profiting from our hard work and costs that include memory usage, bandwidth and server loads all of which are far greater when used by your submitter than those created by the members who post by hand because of the speed with which your scripts will be adding jobs to our server.

Yes, our members may benefit from the new members you might bring in. However there seems to be a new submitter starting each week and as quick as they come many also go.  Others are simply out for a quick dollar and are not concerned how they effect the safelist's and our resources and simply end up providing nothing but maybe some duplicate memberships.
