The content of the Discover tab is curated (reviewed) by Wyze before anything is posted there. Videos are submitted by sending to wow@wyze.com or by post on the forum in the #captured-on-wyze category. More info on that is here: Wyze Discover Feedback Thread!.
Submissions are required to conform to the Wyze Community Guidelines. So no worries, explicit content will not make it into the Discover section.
