Breastfeeding: Breastfeeding content where a child is present, even with visible areola, can now earn ad revenue. Previously, such content was only monetizable if no areola was visible. Also, breastfeeding thumbnails with focus on breasts without visible areola can now earn ad revenue.

Sensual dancing:  Non-sexually graphic dancing involving rhythmic body movements, such as twerking or grinding, as well as dance featuring fleeting minimal clothing can now earn ad revenue. Previously such content was not considered monetizable.
