Хак один IP = один просмотр

вопрос

есть такой хак

1) Через phpmyadmin делаем запрос

ALTER TABLE `*ПРЕФИКС*_post` ADD `ip_views` TEXT CHARACTER SET cp1251 COLLATE cp1251_general_ci NOT NULL;

где *ПРЕФИКС* - ваш префикс таблиц бд.

2) Находим в engine/engine.php

Показать / Скрыть текст

if (! $newsid) $sql_news = "SELECT id, autor, date, short_story, full_story, xfields, title, category, descr, keywords, alt_name, comm_num, allow_comm, allow_rate, fixed, rating, vote_num, news_read, approve, votes, access, flag, editdate, editor, reason, view_edit, tags, metatitle FROM " . PREFIX . "_post WHERE alt_name ='$news_name' AND date >= '{$year}-{$month}-{$day}' AND date < '{$year}-{$month}-{$day}' + INTERVAL 24 HOUR LIMIT 0,1";
                else $sql_news = "SELECT id, autor, date, short_story, full_story, xfields, title, category, descr, keywords, alt_name, comm_num, allow_comm, allow_rate, fixed, rating, vote_num, news_read, approve, votes, access, flag, editdate, editor, reason, view_edit, tags, metatitle FROM " . PREFIX . "_post where  id = '$newsid'";

меняем на

автор хака keiZ, так вот что меня интересует...
Сильно ли он грузит сервер? А то хочу сделать оплату релизерам за просмотры их новостей... но без подобного хака это невозможно...
