Zango's consumer website asserted that the company was "committed to creating a content economy built on a foundation of safe and ethical practices by protecting consumer privacy while offering a fulfilling and high-value content experience." It provided targeted advertising in return for partner companies' content such as sports, comedy, dance, erotic videos, online games, and screensavers. Warner Bros. and others had provided content, but WB terminated its business relationship with Zango after concerns were raised that children viewing Warner Bros. content could be exposed to advertisements for pornography.
StopBadware.org lists a number of undesirable behaviors associated with Zango Easy Messenger, including "behaves as spyware", "automatically runs on startup", "displays pop-up advertisements", "installs adware", and "bundled software cannot be closed". The same site states, "We find that Zango Easy Messenger is not badware, although it does engage in behaviors that users should be aware of."
Websense has a Zango-related security advisory dated November 2006, stating that "Websense Security Labs has discovered a number of user pages on the MySpace domain which have videos that look like they are from YouTube. The videos have an installer embedded within them for the Zango Cash Toolbar. When users click on the video, they are directed to a copy of the video, which is hosted on a site called 'Yootube.info.' ... the video downloads and attempts to install setup.exe from Zango Cash."
A more detailed analysis of this attack, according to one website, is that "Zango continues numerous practices likely to confuse, deceive, or otherwise harm typical users as well as practices specifically contrary to Zango's obligations under its November 2006 settlement with the FTC." These include failure to include on-screen disclosure of material terms, widespread in-toolbar ads without labeling and hyperlinks, ads for "bogus sites that attempt to defraud users", and third party installations without disclosure.
