A coalition of Hollywood workers and gay rights advocates is calling on the industry website IMDb to stop publishing the birth names of transgender performers and others without their consent, a practice known as “deadnaming” that detractors say perpetuates discrimination.

“To reveal a transgender person’s birth name without th eir explicit permission is an invasion of privacy that only serves to undermine the trans person’s true authentic identity, and can put them at risk for discrimination, even violence,” said Nick Adams, director of transgender representation at Glaad, the organization that tracks media representations of lesbian, gay, bisexual and transgender people.

On Wednesday, the group announced that it, along with other gay and transgender rights organizations, was backing a legal challenge being mounted by the Hollywood union SAG-Aftra to stop IMDb from publishing certain personal information about Hollywood performers and other professionals.

In a statement, an IMDb spokesman said the company “is committed to being the most complete source of film, TV and celebrity information,” and that it “strives to represent an individual’s gender identity while also accurately reflecting cast and crew listings as they appear in a production’s on-screen credits at the time of original release.”
