Frontier Communications needs a lesson in how to redact documents.

Frontier is trying to hide large portions of an audit report from the public, claiming that details about the ISP’s broadband-network problems are trade secrets. But when Frontier made a redacted version of the report public, many of the blacked-out parts were still readable simply by copying and pasting from the document.

The Frontier-edited version of the 164-page report, which was ordered by the West Virginia Public Service Commission (PSC) and written by a consultant firm, includes about 80 redacted exhibits and many pages that have been fully or partially blacked out.

(Update: It turns out some of the exhibits weren’t properly redacted, either.)
