Question for other link list owners

[Useless]

I'm going to sound retarded now, but we all know that that doesn't bother me.

I was born after most link lists had canned their AVS listings, but have seen the old AVS rules on a few submission pages. I never quite understood why the reviewer would require a user/pass for an AVS site. Wouldn't that be akin to asking for a password to a paysite being promoted by a free site? Also, would AVS sites perform better (sales wise) if there were some clickable samples on them?

I know there a few people who submit free sites which promote their own mega-AVS sites since it's difficult to get the AVS site itself listed anywhere. Does this approach seem to work well (if anyone is willing to fess up)?

One more question to those of you who build AVS sites. Do you make more money selling the AVS itself or through upsells to a premium AVS membership - or even a standard sponsor being promoted on the site? I'd fully understand if you didnt want to answer my $$$ questions.
