http://openid.aliz.es/username where username is a token of your choosing.
It will validate everything, it doesn't care. It is anti-identity. Perhaps IPs are logged, I don't know. Just because someone uses this it doesn't mean it is my fault. It is your fault for using openID. If you're angry that someone is using it, then you don't understand the design of OpenID.
OpenID was meant to allow you some control over an identity. Well I don't want an identity, especially now. So this is for all those out there who don't want openID but don't want to register as anything else.
Another great site is http://spam.la . Much like this site but for email!
