LOL, what are you talking about?
fuck, so i just re-read the original post.
i mean to say... don't change it as in delete it.
change the pics and linking code on a mass edit. 100 big tit galleries, use the same pictures for maybe every 5 galleries. if someone notices, then fuck 'em. they'll wonder how the same page was listed twice. but why would they care? heaven forefend someone might use the same picture more than once.
you really think that someone like the hun will see your gallery has been changed from busty amateurs to boobtropolis, and go on a blacklisting spree? unlikely. the guy has problems catching real cheaters when they redirect their traffic to popup hell. if you've ever seen them on his index page, you'll know that they stay up there for like 12 to 15 hours before he removes the link. he has a bot, eh? must be a pretty shitty one. "bot" my ass.
it has been a long time since i did gallery pages. obviously it is awful, awful traffic compared to avs. anyway. i have pages in the hun's archive that have been changed dozens of times since he listed them. guess what? even pages where i've changed images, but kept them in the same niche... they're still there alive and kicking, and listed.
