The story of F U C K.com is one of litigation dating back to the mid 1990's. The domain was for years registered and deposited in the court. My guess the litigation ended , the domain was transferred and this triggered the recent whois date. Loans.com shows a whois "creation" date of Feb 15, 2000 when this was infact the transfer date as opposed to the initial creation date.
Why I like f-ck.us is because f u c k.us is censored so this is the best that it gets. And unlike the .com I feel the censorship in .us is on very solid ground because of the advance warning and the widspread as opposed to selective application.
But I agree f-ck.us is a bet on censorship in the .us tld
