This is taken from the
TAFL Rules page:
It is up to you whether you update your list manually, or use a specific program that allows people to join and you approve from an admin panel (like phpFanBase or Enthusiast). Forms and scripts that add people as soon as they submit their information are no longer allowed. This includes Megabook and other guestbook programs. Subjects using these types of scripts will be required to switch to one of the above approved methods, or will be removed from the network. This form of auto-add script has been abused, and many a good subject been neglected by lack of effort on the part of the owner, forcing us to enforce this rule strictly.
As we are now over the initial transition period and the network is running smoothly, staffers will now be enforcing this rule. If you use this type of script, your site will be placed on troubles and you will need to switch to another method. As stated above, this is due to continual abuse and neglect by some owners using guestbook scripts. We hope that through this rule, fanlistings will be better taken care of. Thanks for your cooperation in this matter!
