These are seller pages, not user pages. Sellers are web indexed by default. You could argue that Coinbase shouldn't index these pages and that they should only be accessible from seller websites, but sellers have already made them public on the WWW. There's no "data leak".

Giving out the emails associated with their accounts is a really bad idea. Having them indexed by Google is even worse, hence the phishing attempts.

Why can't those stay anonymous?
