If you're using name.com's DNS, then they've basically got a wildcard subdomain that points to a spammy domain-parked page.

So, say you have valid records for .yourdomain.com and www.yourdomain.com. Those two hosts will resolve as you would expect them, but *.yourdomain.com will resolve to a spam page.

Wow, that's pretty evil. I definitely won't be using name.com (I've been happy with Dreamhost as a registrar for years anyway, but would be interested in trying someone else in the future). Thanks for the heads up.
