From the developer:
AdLock for Safari is an ad-blocking extension that doesn’t support acceptable ads. Unlike the other popular ad-blocking extensions, AdLock blocks all ads by default. Therefore, you won’t be forced to white-list any websites or any advertisers. Also, AdLock shields your confidentiality and protects you from tracking, spyware, and dangerous websites. Without heavy banners and ads, all web-pages load much faster.
