Simulation of site visits via Cron, there are ready solutions or suggestions?

There are 100500 accounts on free hosting. :))
Different IP. There is a system of "Rotator" on a VPS (change links according to the algorithm: uniqueness, recurrence, etc...). Need script for Cron actually executes the "view" of the site.
algorithm:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "); //Link
curl_setopt($ch, CURLOPT_USERAGENT, "); //the UserAgent
curl_exec($ch);
curl_close($ch);
?>

a stuck rotator.
"Cashing in" using jetswap and websurf not offer: banned more than 50 accounts, stop!
What are the options?
