Reading the comments below, am I safe if I have my domain name registered with Namecheap? How can I make sure that this won't happen to one of my sites? Is this Godaddy specific or all domain name registrars affected by this? What about non-US registrars (can you guys name some)?
Any .com, .net, .org, .biz, .us, .tel, and .travel domain is subject to seizure by a US court order. What company you register the domain at (and what country it's in) is irrelevant since the registry itself (Verisign for .com/.net/.org, NeuStar for the others) is in the US.
