Or, maybe add the exclusion box as part of the search settings.
This would help eliminate those sites that one has to sift through to find what they want.
My search exclude would look like this:
-zoominfo.com -linkedin.com -facebook.com -mylife.com -whitepages.com -spokeo.com -legacy.com -truepeoplesearch.com -radaris.com -yelp.com -tripadvisor.com
Now, I know that those sites will not like this, but I, and I dare say the millions of other users, would love it.
