sitelock 

A sitelock helps protect browser-based computer games from being spammed or hacked after they are uploaded to the internet. Sitelocks help protect original content created by game developers. It is recommended that a developer integrates a sitelock into their game before they release it online.

"I should have put a sitelock on my game Konkrete Madness, because it only took a few days before it became overloaded with popups and spam!"
