As your users import contacts and build your social network, you may want to automatically block certain emails/contacts from being published. This is especially useful to block bots or group lists. Here's how to do it.
Add Blocked Emails
Go to the Admin link in the account dropdown.
Go to the Settings page and click the Who Knows Who tab.
Either manually enter in comma-separated emails or simply copy and paste the list into the "Block these email contacts" field.
Click the Add button, and you'll see the list of newly blocked emails added below.
Remove Blocked Emails
To remove blocked emails, find the email in the "Blocked Emails" list.
Click the delete button next to the email to remove it from the black list.
