Welcome to the Q&A Forum

I will send details to help@moz.com

Thank you.

Beginning in early in Feb, we got a big bump in duplicate pages.  The URLs of the pages are very odd:

Example URL:
http://firstname.lastname@website.com/dir/page.php
is duplicate with  http://website.com/dir/page.php

I checked though the site, nginx conf files, and referral pages, and could not find what is prefixing the pages with 'http://firstname.lastname@'.

Any ideas?  The person whose name is  'Firstname Lastname' is stumped as well.

Thanks.
