I use sneakemail.com as a way of filtering mail and tracking email addresses I give out to web sites and mailing lists (/not/ as 'disposable' addresses), and both their domains (sneakemail.com and the newer snkmail.com) are blocked by this service. Blocking these email addresses is counterproductive. The only site I've encountered in the past that blocked Sneakemail was Digg, and I didn't sign up as a result. They /may/ have blocked a few 'disposable' accounts with this strategy, but they /definitely/ lost at least one 'real' user because of it. In addition to this, I have no doubt that there were orders of magnitude more 'disposable' Hotmail and GMail addresses signed up for Digg that there would have been Sneakemail addresses, so they need to deal with the 'problem' of undetectable disposable accounts anyway. Sneakemail is a great service, BTW. I hope stuff like this doesn't render it useless.
