Causes spammy pop-ups to intermittently show up on sites where it’s installed, even when you don’t necessarily visit a page with a plugin. Apparently this is secretly embedded in their Terms of Use, based on the JavaScript that connects with an ad server… in other words, not hacked, just malware. AVOID! There are better captcha solutions out there.

They inject ads that make you download viruses that harm your browser and your computer. I thought was hacked!

The plugin injects the site with malware. This may get your site banned from Google and all the major search engines. As I seen in other reviews, they inject the sites that have the plugin installed to monetize the plugin. My recommendation is to skip this one.

Thank you for creating this plugin. Working well with WordPress 4.1, and self-child-theme, which is based on the TwentyTen theme with other plugins installed.

This causes security check and calls to be made outside your website, instead of keeping security within your website. Images and calls are made to outside a WP site installation and to a 2nd or 3rd party server. ?? Too bad.
