Boycott GoDaddy
Godaddy.com honestly believes they should police the content hosted on sites, and when they object, they pull domain names. Most recently, they pulled ratemycop.com, but it has happened before, and it has made a lot of people angry. I have registered a number of names with them in the past, and as they come up for renewal, I've been moving them to another registrar. It's not as though I post anything interesting enough to be pulled, I just don't think behavior like that is appropriate for a domain registrar.
