wow $50? save that 50 and buy yourself something more useful buddy . As for your question, once listed, they can not do anything about it or remove your link, it is not up to them. This company is not really helping you that much, if not they are probably ripping you off. Cause for most major search engines out there, including google, you can simply submit your site yourself, same case for many other major search engines.

My advice to you is that get more affiliates that are almost in the same category as your site and update your site commonly with useful content that would make the visitors come back. Also for some site categories, joining popular topsite directories will also help.

good luck to you,
Sean
