PHP

        public function is_bot(){
            $override = apply_filters('pre_nebula_is_bot', null);
            if ( isset($override) ){return $override;}

            if ( $this->is_googlebot() ){
                return true;
            }

            if ( !empty($this->super->server['HTTP_USER_AGENT']) ){
                $bot_regex = array('bot', 'crawl', 'spider', 'feed', 'slurp', 'tracker', 'http', 'favicon', 'curl', 'coda', 'netcraft');
                $all_bot_regex = apply_filters('nebula_bot_regex', $bot_regex);
                foreach( $all_bot_regex as $bot_regex ){
                    if ( strpos(strtolower($this->super->server['HTTP_USER_AGENT']), $bot_regex) !== false ){ //@todo "Nebula" 0: Update strpos() to str_contains() in PHP8
                        return true;
                    }
                }
            }

            if ( $this->is_slackbot() ){ //The regex above should already capture this
                return true;
            }

            return false;
        }

Override

To override this PHP function, use this hook in your child theme or plugin ("my_custom" can be changed):

PHP

add_filter('pre_nebula_is_bot', 'my_custom_is_bot'); 
function my_custom_is_bot(){ 
    //Write your own code here

    return true; //Return true to prevent the original function from running afterwords
}

You can completely disable this PHP function with a single line actions:

PHP

 add_filter('pre_nebula_is_bot', '__return_false');
