It does not protect feeds.
But we will consider it for a future release.
To turn off feeds, you can put something like this in your theme/functions.php
function stacy_disable_feed() {
wp_die( __('No feed available,please visit our <a href="'. get_bloginfo('url') .'">homepage</a>!') );
}
add_action( 'do_feed', 'stacy_disable_feed', 1);
add_action( 'do_feed_rdf', 'stacy_disable_feed', 1);
add_action( 'do_feed_rss', 'stacy_disable_feed', 1);
add_action( 'do_feed_rss2', 'stacy_disable_feed', 1);
add_action( 'do_feed_atom', 'stacy_disable_feed', 1);
add_action( 'do_feed_rss2_comments', 'stacy_disable_feed', 1);
add_action( 'do_feed_atom_comments', 'stacy_disable_feed', 1);
add_action( 'bp_activity_sitewide_feed', 'stacy_disable_feed', 1 );
add_action( 'bp_activity_personal_feed', 'stacy_disable_feed', 1 );
add_action( 'bp_activity_friends_feed', 'stacy_disable_feed', 1 );
add_action( 'bp_activity_my_groups_feed', 'stacy_disable_feed', 1 );
