Since it is now listed on the site, I took a look their service, I am not a user yet though. Here is the question about the service, that puzzles me (judging from the description on site): once you sign up for the service you get .anonaddy.com (or .me) domain, which you can use for registration on various sites by just prefixing it with anything you like (i.e. something@.anonaddy.com). By default all addresses *@.anonaddy.com will be valid, and will redirect mail to your account. If some spammer finds out one of your aliases (e.g. something@.anonaddy.com) you can then block emails sent to this particular alias. What I do not understand is what is the point of it all, if any *@.anonaddy.com email is valid (until explicitly blocked by user), because if this is the case, then it is enough to know any of your *@.anonaddy.com emails, to spam the hell out of you (by just sending emails to @.anonaddy.com).
What am I missing here (if anything)?
P.S.: I have also posted the same question on reddit.
