godaddy... I never try to use it because I always get a lot of negative comments about it. However, there are still many people use it.
Thumb down for their service. They will quickly block your domain name once they get complaint from someone about spamming. They'll not ask you first... they'll block it first and then it comes your turn to explain to them... if you can give hundred of good reason to them, you'll be given a green light to get back your domain name. However, usually it takes time.
