don't expose emails from ssh keys, jabber ids and gpg keys in launcpad

Hi,
- when one sets a jabber id it's visible to unlogged users (whole world including spammers). Jabber id is often one's email
- when one uploads an ssh key its comment is visible to unlogged users. Ssh key's comment is often one's email
- when you set a gpg key its id and link to its details containing email is visible to unlogged users

Why not to make these things visible only to logged users? Or even better only to users with active gpg key?

Thanks
