I'm up for anything that'll make it easier for me to get listed.
I think even more gallery makers would see the benefit in this if there was even greater insentive... actually, what both RS and Darksoft suggested is pretty clever. What if there was an auto/semi-submitter that only worked with the TGP's that were in this program and that using this submitter was the only way to submit to them? If all the gallery addresses were stored in a single database, a bot could be made to constantly check the galleries hourly to look for cheaters.
I think the biggest hurdle to tackle would be how to prevent duplicate accounts.
