Comment 3 for bug 523093

Reading your answer again, I would rather say it should not only obfuscate but totally remove my launchpad e-mail address. The launchpad e-mail address should only be a means for launchpad to send me messages, and not be used as any identification. So if an e-mail address is really needed for publication, it should not pick one on basis of any launchpad user, but use some address that has been used for gpg-signing, from the original Debian upload for instance.

The "preferred contact address" setting in launchpad is "for all Launchpad e-mail" and not for humans to discover and use.

I have of course checked "Hide my email addresses from other Launchpad users".
