I needed to restrict participant topic creation to selected forums but allow replies to all topics in all forums. I came up with this solution

function my_bbp_restrict_topic_creation( $can ) {
		
	$forum_id = array(18,22,56); //change your forum id

	if ( ! bbp_is_user_keymaster() &&  bbp_is_single_forum() &&   !in_array( bbp_get_forum_id(),$forum_id) ) {
		$can = false;	
	}

	return $can;

}
add_filter( 'bbp_current_user_can_publish_topics', 'my_bbp_restrict_topic_creation' );  

Participants can only create topics in the three forums with IDs 18,22,and 56. Whereas the KeyMaster can create topics in all forums.
