Comment (by wdfee):

 Hi @DJPaul
 in our case the networks don't have subblogs, so we can use
 `is_user_member_of_blog()`, my filter function's like this:

 {{{
 function my_activity_mentions_usernames_filter($usernames) {
         foreach( $usernames as $u => $username):
                 $mentioned_user = get_user_by( 'login', $username );
                 if( empty($mentioned_user) ||
 !is_user_member_of_blog($mentioned_user->ID) ):
                         unset($usernames[$u]);
                 endif;
         endforeach;
         return $usernames;
 }
 }}}

 In bbPress btw there's an equivalent filter offered a little bit later in
 `bbp_find_mentions()` includes/extend/buddypress/functions.php 346.
