I think the warning page is an excellent practice. Responsible parents will have the filtering software on, yes, but use it as a teaser like a lot of the top-rated paysites do. Done right, a warning page is not only excellent SEO fodder, but a great place to tease your visitors. Most of the sponsor programs I work with offer me the option of sending my traffic where I want. As freesites are often more of a mini-tour, visitors can be sent to the join page. The smart ones still do warning pages.
