Copyscape Premium Reviews
The plugin is not working
The plugin is not working. I paid for the service, checked all the settings. After pressing the check button, the page is updated, but nothing changes, and the limits are not written off. This
worthless plugin, reporting cookie consents as plagiarism
I’ve spent 15$ to get hundreds of matches for… cookie consent pop-up. What a BS.
The plugin works great for detecting plagiarism
I personally installed the plugin in my site to detect plagiarised content that i did not notice before. and well just for 10$ I got almost unlimited credits to check for it on product and posts pages
