Please use the following code to hide the button

/**
 * @param array $args button args.
 * @param int   $leader_id leader to be followed.
 * @param int   $follower_id follower id.
 *
 * @return mixed
 */
function buddydev_hide_unfollow_button_for_users( $args, $leader_id, $follower_id ) {

	if ( 'following' !== $args['id'] ) {
		return $args;
	}

	// user ids who can not be unfollowed.
	$special_user_ids = array( 1,2,3,67 );

	if ( in_array( $leader_id, $special_user_ids ) ) {
		$args['id'] = '';
	}

	return $args;

}
add_filter( 'bp_follow_get_add_follow_button', 'buddydev_hide_unfollow_button_for_users', 10, 3 );

It only hides the button but does not do anything else to stop unfollowing.

Thank you.

HI Julia,
If it is not there, please Contact your theme developers. That is the most common place to have these.

Hi David,
Welcome to BuddyDev.

A. What is the criteria for redirecting users from profile to author page?
1) A logged in user should be able to visit their own profile?
2) Other visiting a user’s profile get redirected to author page for the displayed user?

B. There is no such plugin available. You are looking for something like google circle. We do have a similar plugin but it is unfinished. We did it by creating custom tables for labelling Friend groups. The Labels are specific to Users.

C. That will be very easy. If you can get the point B working, a simple pre_get_posts filter like above will do it.

Also, BP profile Visibility or Blog Categories for Groups won’t be much help with this.

Best Regards
Brajesh

You are right, that code was for older version of BuddyPress.

Please remove that and use the following

/**
 * Filter and remove admin and logged in users from all BuddyPress auto complete box.
 *
 * @param array $args BP_User_Query args.
 *
 * @return array
 */
function buddydev_filter_buddypress_auto_complete_ids( $args ) {
	$user_ids = isset( $args['exclude'] ) ? $args['exclude'] : array();

	if ( $user_ids && ! is_array( $user_ids ) ) {
		$user_ids = wp_parse_id_list( $user_ids );
	}

	$excluded = get_users( array( 'role' => 'administrator', 'fields' => 'ID' ) );

	if ( is_user_logged_in() ) {
		array_push( $excluded, get_current_user_id() );
	}

	$args['exclude'] = array_merge( $excluded, $user_ids );
	return $args;
}
add_filter( 'bp_members_suggestions_query_args', 'buddydev_filter_buddypress_auto_complete_ids' );
