Shouldn't show email addresses...

I was checking out the Top Users leaderboard, and after figuring out that each user has a unique number identifier, I checked out some random other users out of curiosity. Many of them haven’t yet set themselves up with a username, and so their email addresses are shown in their place. Most of us don’t like our email addresses seen—especially if there’s a chance they could get absorbed by email bots.
My suggestion is that instead of having the email address visible on the user’s page and in the title of the page, it should be something like User1021 instead.
