Where do I report copyright infringements, libel, and other legal issues?
You don’t! WordPress.org does not host sites. WordPress.org provides publishing software that anyone can download and use. The organization, WordPress.org, has no control over who uses the software or how they use it. In other words, WordPress.org does NOT have the power to take down comments, posts, sites, or anything else. Perform a whois lookup to track down the operator or host of a particular site, then report the infringement to those organizations.
