Your experience among many others were impacted by this update: Strengthening Our Safety Policies and Tools
Almost all Social Hangout experiences were affected due to how quickly we wanted to move. If you don’t think your experience is subject to the new policies, please submit an appeal and we will review as soon as we can! In the appeal, please choose Moderation > Other content I created as the categories.
The owner of the experience should also have receive a Roblox Message with details too.
