Facebook has no plans to end its controversial "real name" policy, but CEO Mark Zuckerberg said the policy can work for those in the trans community advocating for its removal.

In a Tuesday Q&A with the public on his Facebook page, Zuckerberg addressed the policy, suggesting it has been misinterpreted in some cases.

"There is some confusion about what our policy actually is," Zuckerberg said in response to a question from BuzzFeed News. "Real name does not mean your legal name. Your real name is whatever you go by and what your friends call you,"

The policy has been a target of criticism for some time. Many members of the trans community go by names different than those given to them at birth and have been kicked off Facebook for using them.

"If you're a marginalised person, such as a trans person, you may be left with no way to get back on," a former Facebook employee named Zip wrote in a recent post to Medium. "Facebook [has] handed an enormous hammer to those who would like to silence us, and time after time I see that hammer coming down on trans women who have just stepped out of line by suggesting that perhaps we're being mistreated."

On Tuesday afternoon, Zuckerberg explained that Facebook does allow names other than legal ones. "If your friends all call you by a nickname and you want to use that name on Facebook, you should be able to do that," he said. In this case, he said, the policy "should be able to support everyone using their own real names, including everyone in the transgender community."

The operative word in the sentence is "should." Though Zuckerberg articulated Facebook's official policy, the execution of that policy has been uneven, according to multiple accounts, including that of Zip.

Zuckerberg also mentioned an internal effort to improve the current system. "We are working on better and more ways for people to show us what their real name is so we can both keep this policy which protects so many people in our community while also serving the transgender community," he said.
