X sounds like a porn site of some kind. Fun fact, the government in India thought the same thing and banned it for that reason...for awhile.
Apparently it's not a well known story, so I'll remind everyone that India's government banned many different porn sites within their own country's internet access.
I don't know if it's at the DNS level or the actual IP address or what, but they banned almost every free porn site I've ever heard of, even more obscure ones like Jizzhut and alphaporno, even really really low budget ones that are just an index for a bunch of embedded videos from other sites
