How to customize the Listing sources that are monitoring for a specific business account:
Impersonate into the account that you would like to change the settings on.
Go to Reputation Management > Settings > Listings
Here you can turn sources on and off by clicking the box next to the appropriate Listing Source. *Note that some sources here will be selected and grayed out, which means they are not editable.
Q: Why are some listing sources grayed out and unable to be edited?
A: This happens when our system has found a relevant listing for the given business on this source. If you are sure this source is irrelevant:
Go to the Primary Listings tab
Find the source you want to remove and select not mine for each of the listing matches on that source. This will then allow you to uncheck the source in the Settings > Listings tab.
