@TeamYouTube @YouTube can content creators please have an option to tag their thumbnail as spoilers? And the viewers should be able to toggle a setting to switch their preference of a spoiler alert for the thumbnail. #nomorespoilers
Great suggestion. You can always let us know your thoughts by using 'Send Feedback' to help us prioritize feature requests: https://goo.gl/WdI0BK . We'll certainly pass along your request to our developers, we're always working to add new features based on viewer feedback.
