If you want an OpenID provider that gives you email aliases so that websites don´t have your private email information, LiquidID is the perfect provider for you. LiquidID is an extension of OpenID in that it provides protection against abuse of your email and works with OpenID accounts such as Springnote, LiveJournal, WikiTravel and others.
LiquidID provides different aliases to the different OpenID enabled sites so that if your email address becomes compromised, LiquidID will reject the compromised aliases. It´s not a spam filter exactly but does allow spam management while ensuring the delivery of legitimate emails without the worry of false positives. Meanwhile OpenID sites can still communicate with you since LiquidID redirects your email to your account.
