Plugin works fine, but "powered by" is unacceptable

This works fine, but I found the “Powered by” attribution unacceptable. There’s no option to turn it off and the styling attempts to block you from removing it. For anyone looking to remove it, this is the styling required in your child theme css:

.wpcr3_clear, div.wpcr3_review .wpcr3_clear { display: none !important; }

Developer needs to keep their ego in check.
