Has anyone ever had a problem paying the $600 to Yahoo and then have them not approve your site and not retrun your money? If I am reading their submission page correctly, it is $600 for adult sites, and it is non-refundable, and does not guarantee a listing.

For sites that include adult content or services, the nonrefundable initial fee is US$600 and the recurring annual fee is US$600. The higher cost for sites with adult content reflects the fact that Yahoo! directory team uses a more complex and time-intensive review process for sites offering adult content and/or services.

Important note: Use of the Yahoo! Directory Submit program does not ensure that your submission will be accepted for inclusion in the Yahoo! Directory. Final judgment on the suitability, placement, and description of all sites submitted to Yahoo! is solely the responsibility of the Yahoo! directory team. For submission guidelines, click here.
