#7451: Adding comments from non-registered users into activity stream.

 There was an old plugin "BP Include Non-member Comments" by @boonebgorges,
 but it does not work anymore.


 I tried to update it, but there is too much new functionality that I would
 have to duplicate too much code. So, I tried to use `comment_post` action
 and adding comments to activity stream, but there are some blocking

 1) Function `bp_activity_post_type_comment()` is checking if user is
 registered: https://buddypress.trac.wordpress.org/browser/tags/2.8.1/src

 2) Function `bp_activity_new_comment()` is also checking if `user_id` is
 available: https://buddypress.trac.wordpress.org/browser/tags/2.8.1/src

 When it is be possible to go through both places (for example with the
 help of some hook), it could be achived easily.

 I did not want to hardcode changes, so I used some kind of cache hack to
 bypass it (adding user with `user_id = 9999999` into user cache before
 BuddyPress will check it):

 add_action( 'comment_post',
 'custom_include_non_registered_comments_into_stream', 8, 2 );
 function custom_include_non_registered_comments_into_stream( $comment_id,
 $is_approved ) {
   if ( $is_approved == 1 ) {
     $comment = get_comment( $comment_id );
     $user = get_user_by( 'email', $comment->comment_author_email );
     if ( empty ( $user ) ) {
       wp_cache_add( $comment->comment_author_email, 9999999, 'useremail'
       $user_object = new WP_User();
       $user_object->ID = 9999999;
       wp_cache_add( 9999999, $user_object, 'users' );

 Everything works now, there are no warnings, but I am not sure if there
 are any possible consequences? I had to use also filters
 `bp_activity_comment_action`, `bp_core_gravatar_email`,
 `bp_activity_comment_name` and `bp_activity_comment_user_link` to
 customize display of these comments in activity stream (especially to
 handle special `user_id = 9999999`), but hook with possibility of adding
 comments from non-registered users (empty or zero `user_id`) would be
 easier and very helpful for some users. I understand that BuddyPress is
 network of registered members, but in this case blog comments from non-
 registered users in activity stream can be also helpful.

 Maybe there is another way to achieve, but I did not find it :-(
