If you have a quality site with good content, and you revoke your credit card before they can automatically recharge you after the year is up, you are basically grandfathered. because Yahoo will not remove quality sites from its directory.
If your site has no unique content, then yes they will probably revoke your listing, so once again content is king.
Anybody with this experience?
Also, my understanding, is that the PR on the first page is distributed amonst the remaining pages in that category, since Yahoo serves the entire category to Google as one page, and only divides it up into 20 listings per page for the user (sort of reverse cloaking).
So if Yahoo has 90 listings in a category, with a PR4 then that PR4 is spread amounst the 90 listings, not just the first 20.
