We’re changing the way we enforce Google+ restrictions for YouTube comments, effective June 21, 2018.
Google+ allows users to set country and age restrictions around who can see their public posts. Previously, the same settings applied for any YouTube comment created with a Google+ account.
Several years ago, we announced changes to using YouTube with Google+. As part of those changes, you don't need Google+ to use YouTube. Therefore, beginning June 21, YouTube comments will no longer enforce these Google+ profile settings.This applies to any comments you’ve made on YouTube.
