| 5 | * This does not make sites available in the Reader—that depends on the public access to /feed/ as a method on the WP.com side |
| 6 | * to check if a site is public. It also does not add any content to the feed. Any content that should not be displayed in the Reader |
| 7 | * or other RSS readers should be filtered out elsewhere. |
| 8 | * |
| 9 | * These hooks were originally part of the now-deprecated Enhanced Distribution. |
