This is a strange one. I keep getting unknown users claiming to be the owner of my website in webmaster central.
I keep removing them but a couple of days later there is a new message like the below
New verified owner for http://www.xxxxx.com/November 27, 2012
A new user has been verified as an owner of http://www.xxxxx.com/:
I have replaced the domain name with xxxxxx
anyone had this before ?
