1. Apply moderation to ProfilePage (near/widget/ProfilePage): Filter Profile Feed based on new moderation format near-discovery-components#376
2. Apply moderation to single post and single comment views: Standalone Post and Comment views incorporate Moderation near-discovery-components#414
3. Block widget feature at gateway or VM level
