Imitation of site visits via Cron, any ready-made solutions or suggestions?

Question

PHP

There are 100500 accounts on free hostings. :))
Different IP. There is a "Rotator" system on the VPS (changing links according to the algorithm: uniqueness, cyclicity, etc...). We need a Cron script that actually "browses" the site.
algorithm:

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, ''); //Ссылка
curl_setopt($ch, CURLOPT_USERAGENT, ''); //Юзерагент
curl_exec($ch);
curl_close($ch);
?>

do not offer - the rotator does not work.
Do not offer "cash-out" through jetswap and websurf: more than 50 accounts have been banned, that's enough!
What are the options?
