I don't know the owner of Sexgrace, but did submit a bunch of sites there over the course of a few months. To this day, have never seen a listing.
Just checked the main page of the site and it shows 'New' sites as of May 31...but not of which year
ExploreXXX used to be a great site. Since it was sold, no idea how far behind it is on reviews. Just checked the site and it does show updates as recently as 8/19/06. So, maybe that's a good sign...
