Will simple adblock block all ads?
Simple Adblock uses the EasyList filters developed for Adblockplus, by the late Rick752 http://adblockplus.org/blog/sad-news/ The filters are generic and are maintained so they will block effectively for most webpages. However as the filters are generic there will be websites where the adblocking will not work. Especially because the EasyList filter is optimized mainly towards websides in english. The filters are today updated by an active community maintained by Ares2.
