Sam Wineburg, an education professor at Stanford, and Nadav Ziv, his student, delved into the .org domain and explain here why it is deceptive.

Readers assume that .org implies a trustworthy site. It does not.

They write:

Dot-org symbolizes neither quality nor trustworthiness. It’s a marketing tool that relies on a widespread but false association with credibility….The dot-org domain is controlled by the Public Interest Registry, which was sold last month to Ethos Capital, a private equity firm. The three letters are marketed as “a powerful signal that your site serves a greater good — rather than just a bottom line.” It’s a claim that leads people to make errors about whom and what to trust.

Unlike dot-gov or dot-edu, which are closed to the general public, dot-org is an “open” domain. Anyone can register a dot-org without passing a character test. Even commercial sites can be dot-orgs. Craigslist — among the world’s largest ad sites — is There are over 10 million dot-orgs, each of which pays roughly $10 per year to register. All you have to do to get one is fill out an online form and provide payment.

Registration fees generated $92 million in revenue for the Public Interest Registry in 2018 alone. In theory these revenues could grow much larger soon — in June, the Internet Corporation for Assigned Names and Numbers, the supervisory body that regulates the internet’s domain name system, agreed to lift price caps on dot-orgs. Still, Andy Shea, a spokesperson for the Public Interest Registry, says it plans to keep the pricing for dot-orgs low, with increases of no more than 10 percent on average a year.

In the Public Interest Registry’s latest marketing blitz, they unveiled a logo painted in “deep royal blue,” a shade they say evokes “feelings of trust, security and reliability.” They tell new customers to expect an increase in “donations, and trust for donors” when they become part of the “domain of trust.”

Noteworthy nonprofits, civic organizations and religious groups have embraced the domain — and so have a host of bad actors. All reaped the benefits of dot-org’s association with credibility.

Educational institutions unwittingly shape misperceptions around dot-orgs. Many colleges and universities, including Harvard and Northwestern, steer students in the wrong direction. They equate dot-orgs with nonprofit groups and issue no warning of the dangers lurking beneath the domain’s positive aura.

Dot-org is the favored designation of “astroturf” sites, groups that masquerade as grass roots efforts but are backed by corporate and political interests. One of these is the Employment Policies Institute, which claims to sponsor “nonpartisan research.” It was actually founded and run by the head of a public relations firm that represents the restaurant industry. Another dot-org, Americans for Prosperity Foundation, says it addresses major social problems through “broad-based grass roots outreach.” In reality, it was founded by the billionaire Koch brothers and many of its “grass roots” activists are paid.

There’s an even bigger risk to equating dot-org sites with do-gooders. Dozens of neo-Nazi, anti-L.G.B.T., anti-Muslim, and anti-immigrant groups bear the dot-org seal. A random sample of a hundred organizations designated as hate groups by the Southern Poverty Law Center found that 49 percent carry the dot-org domain.

Reader, beware!
