To Syed Balkhi’s credit, he points out that the plug-in he’s pointed you at doesn’t actually do what it claims to do. And thank goodness Syed points it out, because the plug-in author … doesn’t.
It’s a cute idea, but until there’s clear documentation that WordPress Guerilla Redacted Text redacts nothing, you need to steer clear.
Oh, and by the way; we don’t much like the way the WordPress Redaction is done, either. A shortcode that works only in the Redacted text plug-in? No go.
