Clubhouse, the invitation-only audio chat app launched nearly a year ago, has run into a security problem, with one user sharing audio chats outside the user base.

Clubhouse hasn’t offered details of the privacy breach, although it has said that recording or streaming audio without the speaker’s permission is against the app’s terms of service. In late February, “an individual temporarily streamed multiple rooms from their own feed to a website,” a Clubhouse spokeswoman said. “This individual’s account has been permanently banned from the service, and we have added additional safeguards to prevent people from doing this in the future.”
