This is a GoDaddy thing, plain and simple. They get one complaint--they shut your domain name down by changing the name servers to NS1.SUSPENDED-FOR.SPAM-AND-ABUSE.COM and NS2.SUSPENDED-FOR.SPAM-AND-ABUSE.COM. Exactly what happened here.
This has been going on for at least SIX years now; see http://seclists.org/nmap-hackers/2007/0 (and I saw a hosting company shut down for similar reasons a year before that.)
Wasn't their support of SOPA enough? When are we all going to wake up? How many times does this have to happen?! STOP. USING. GODADDY.
