+- `facebook.com` (44)
+- `facebook.net` (45)
+- `googletagservices.com` (39)
+- `twitter.com` (34)

+   * facebook.com * block
+   * facebook.net * block
+   * googletagservices.com * block
+   * twitter.com * block
+   facebook.com facebook.com * noop
+   facebook.com facebook.net * noop
+   twitter.com twitter.com * noop
