Scrapebox has a built-in Pinger? I see that it has "ping mode", but that sounds
like referer spamming to me. There are plenty of scripts around, paid and free,
but you will need proxies or none of your pings will get through. And you may
not even know that they are failing, depending on the code of the script. So,
you'll need to scrape proxies, then test those proxies for connection and for
anonymity. Or you could just outsource your pinging for a reasonable price.
Google 'bulk ping service'
