what are your plans? think of all the dirty word combos you can and squat on them? I'll help you with some choice words!!!
anyway, prolly not a good idea. first, it's an additional domain ext. meaning there was a gold rush back in the day for Tomcruise.com, because only .coms existed. Now porn sites have the option to use .com, .xxx, .biz, whatever.
second, I'm sure porn sites are also aware of the new domain, and they will be jumping on it along with the squatters.
besides, most porn sites like using clever adjectives, or double entendres. It's not hard(see I just used one!!) to come up with a new one. somebody take my chickenandporn.xxx domain???? I'll just use pornandchicken.xxx, or even chickenandporn.com.
the goldrush of .com squatting came more from reserving proper nouns of big stars like tom cruise and what not. I guess some people were taking up and comers(again! with the word play!) and registering their names before they really made it big(wow, I just can't stop!) I still think it's no good as porn stars and up comers always use a stage name, and even then, they sometimes use multiple stage names. Whitney wonders is AKA Lotta Tops. also, porn stars rarely stay in the biz longer than a few months to a few years. it's a tough demeaning job, and there's a lot of drugs involved as well as danger that some women answered casting calls to very shady operations leading to a beating or death.
