That sounds kind of odd because Scrapebox is already an automation tool, but you can think of it like this - Scrapebox is the swiss army knife of Internet Marketing/SEO. So just like a swiss army knife scrapebox has many functions, and many of those functions can be combined to achieve various outcomes for your SEO purposes.
The Automator allows you to automate the combining of functions to achieve your goals. Be that having an every flowing source for testing public proxies or maybe you want to regularly build links, or perhaps you just want to do some whitehat SEO.
Whatever your goals, the individual functions can be automated, combined, looped and even allow external batch scripts and programs to be part of the process.
The automator is a premium plugin, which means it requires a scrapebox license and is a small additional cost.
