      "value": "Mastodon is a free, open-source social network server based on ActivityPub. In versions before 4.4.6, 4.3.14, and 4.2.27, disabling or suspending a user account does not disconnect the account from the streaming API. This allows disabled or suspended accounts to continue receiving real-time updates through existing streaming connections and to establish new streaming connections, even though they cannot interact with other API endpoints. This undermines moderation actions, as administrators expect disabled or suspended accounts to be fully disconnected from the service. This issue has been patched in versions 4.4.6, 4.3.14, and 4.2.27. No known workarounds exist."

      "value": "Mastodon es un servidor de red social gratuito y de código abierto basado en ActivityPub. En versiones anteriores a la 4.4.6, 4.3.14 y 4.2.27, deshabilitar o suspender una cuenta de usuario no desconecta la cuenta de la API de streaming. Esto permite que las cuentas deshabilitadas o suspendidas continúen recibiendo actualizaciones en tiempo real a través de conexiones de streaming existentes y establezcan nuevas conexiones de streaming, a pesar de que no pueden interactuar con otros puntos finales de la API. Esto socava las acciones de moderación, ya que los administradores esperan que las cuentas deshabilitadas o suspendidas estén completamente desconectadas del servicio. Este problema ha sido parcheado en las versiones 4.4.6, 4.3.14 y 4.2.27. No existen soluciones alternativas conocidas."
