I have completed a PHP library called Shieldon.
The idea of creating it is because of one of my website’s content was stolen, and I saw the spammer built a mirror site to make money from Ads on the site full of articles without original authors’ authorized.
When I have completed this PHP library, I think, Why not release it to public use?
The online DEMO, you can visitmy personal blog, try refreshing it two times in a second.
Shieldon is MIT license. Any suggestion is welcome.
