The privacy of Rewards member e-mail addresses? (Revisited)

On April 23, someone posted a link to a public Brierley.com website where anyone could look up any Borders Rewards member by Rewards card number, e-mail address, or phone number (last 7 digits only).

That public website is still there today. Modifying an account is now disabled but lookup still works. Was this site ever taken down after it was revealed here, or did someone mistakenly put it back up?

(This post is member-locked to discourage Google, Bing, DukGo, etc. from finding it.) Not anymore -- see first comment by rufinia

ETA, August 2, 11:50 am: The web form at Brierley.com is no longer publicly available. You just get a blank page now. Thank you, whoever got this fixed.
