Hello, I would like to get a list of sites my competitor owns. I know some of the sites, and private domain registration is used for them, so it's impossible to match all sites just by looking at whois data (using various services). I found a service called SameOwner.com that allows to search for sites with same account ID for AdSense and Analytics, but the list of sites it returns is probably incomplete. Any other options to list all sites by competitor? Thank you for your answers in advance!
