YouTube is expanding its revamped direct messaging feature from an initial trial in Poland and Ireland to 31 European countries. This feature, available to signed-in users aged 18 and older, allows users to send direct messages and share videos within the YouTube app. The messaging remains experimental and is focused on one-on-one or small group interactions rather than creating a comprehensive social inbox. Users in the United States and other regions are not part of this trial. The age restriction and invite acceptance requirement aim to enhance safety and privacy. YouTube is implementing moderation tools, spam controls, and reporting mechanisms to ensure user protection. The effectiveness of this feature could influence future developments and potential global rollout.
