Collect.xxx and Collector.xxx
 

Here's an example where .XXX is a more focused brand than .COM:

Collect.xxx

There's no way you could get the same idea across in 1 word with any preexisting extension. Nobody (myself included) really loves the ICM Registry, but I think everybody can agree with what I just said.

Collectors pay money to collect. And the very best customers to have in adult entertainment are THESE PEOPLE. Why? Because they buy instinctively, buy everything in their niche simply to have everything, buy old stuff, buy new stuff, and they buy long-term. This is a brand for them.

I also can sell this as a package with multiple variants in .XXX and .COM. You can own the whole space in terms of branding.

Obviously, there are a lot of searches for "collect" and "collector" and "collectible" and "collectable". 100% of the people doing the searching are interest in erotica in some form or another -- whether that's hardcore fetish porn or romance novels, vintage orgy scenes or solo glamour models. You can build an ecommerce store or a subscriber base that pre-pays for adult scenes and images.
