Copyfight prevents your content from being copied. In terms of copy paste. No need to use a plagiarism checker. Prevention is better than cure! Good for SEO, your content remains unique!
I am sorry, but real black hat seo doesn't use copy paste to take your content, they use curl and other types for getting content and scrapping format, some use RSS but if that's not available curl is the way. This plugin will only make the life of your real visitors a nightmare if they decided to copy something. Thanks anyway could be useful to block something, but use bad behavior or cloudflare anti scrap that's more of a professional option.
curl does not work to get the content protected by Copyfight. Period. Actually, nothing does work to copy Copyfight protected content. Try it and we might talk later.
Trying it right now! I will try to curl and if it really does work, I will write a review about this! Edit: I postpone it to another time.
