What's quitting going to do? For every five guys who quit, the site will get fifteen new members.
More work in store for Buzz Aziani (Aziani.com), Holly Randall ([nobabe]HollyRandall[/nobabe].com, Suze Randall (Suze.net), and Mark Lit (J. Stephen Hicks' Digital Desire), Foxes.com, and GlamourGirlsGoneBad.com, Mac & Bumble, Penthouse.com, and Teasums.com, etc, etc. etc.
Update
My mistake -- it was GlamourModelsGoneBad.com. Then you have Michael Scott and all his sites, Tim Jahns and all his sites, and last but not least, Anton Fury and his sites (Gentonline.com, Furypix.com), etc...
