Hi Richard,
I just saw that you already purchased the plugin. Please let me know if you will like to continue with activity rate limiter or I can issue the refud for it.

Hi Richard,
Please do not use above snippet. It won’t work.

Will it be good enough If I can put an example using roles or member types(please let me know which one you will prefer)?

Sure,
Here is an example using role.

I have broken it into 2 functions for defining role based limit and then getting user specific limits.

After that, there are two functions attached to filters. All you need to modify is the first function that supplies role based limit.

/**
 * Get the applicable limit for the given role.
 *
 * @param string $role role name.
 *
 * @return array
 */
function buddydev_custom_get_role_based_activity_limit( $role ) {

	// duration- in minutes
	// limit - how many in that duration
	$limits = array(
		'administrator' => array(
			'duration' => 1440,
			'limit'    => 0,
		),
		'editor'        => array(
			'duration' => 60,
			'limit'    => 10,
		),
		'author'        => array(
			'duration' => 60,
			'limit'    => 5,
		),
		'contributor'   => array(
			'duration' => 1440,
			'limit'    => 20,
		),
		'subscriber'    => array(
			'duration' => 1440,
			'limit'    => 10,
		),
	);

	$default = array(
		'duration' => get_option( 'bp_rate_limit_activity_throttle_duration', 5 ),
		'limit'    => get_option( 'bp_rate_limit_activity_count', 5 ),
	);

	return isset( $limits[ $role ] ) ? $limits[ $role ] : $default;
}

/**
 * Get the limit/duration for the given user.
 *
 * @param int $user_id user id.
 *
 * @return array
 */
function buddydev_custom_get_user_activity_limits( $user_id ) {
	// since a user may have more than 1 role, which of the limit should we use? I will go with the highest allowed.
	$allowed = array(
		'duration' => 0,
		'limit'    => - 1,
	);

	$user    = get_user_by( 'id', $user_id );

	if ( ! $user ) {
		return $allowed;
	}

	foreach ( $user->roles as $role ) {
		$limit = buddydev_custom_get_role_based_activity_limit( $role );

		if ( $limit['limit'] > $allowed['limit'] ) {
			$allowed = $limit;
		}
	}

	return $allowed;
}

/**
 * Filter activity count.
 *
 * @param int $limit limit applied for the specified duration.
 * @param int $user_id user id.
 *
 * @return mixed
 */
function buddydev_custom_filter_ra_activity_count( $limit, $user_id ) {

	$config = buddydev_custom_get_user_activity_limits( $user_id );

	return isset( $config['limit'] ) ? $config['limit'] : $limit;
}

add_filter( 'bp_rate_limit_activity_count', 'buddydev_custom_filter_ra_activity_count', 10, 2 );

/**
 * Filter duration
 *
 * @param int $duration duration in minute
 * @param int $user_id user id.
 *
 * @return int
 */
function buddydev_custom_filter_ra_activity_throttle_duration( $duration, $user_id ) {

	$config = buddydev_custom_get_user_activity_limits( $user_id );

	return isset( $config['duration'] ) ? $config['duration'] : $duration;
}

add_filter( 'bp_rate_limit_activity_throttle_duration', 'buddydev_custom_filter_ra_activity_throttle_duration', 10, 2 );

Hope that helps.
