I think she wanted a new rule, she had created 10 mins rules for other social medias so that her child could use them on the browser if other children sent links but she didn't want her downloading the apps and getting sucked in. My guess would be she would have rather us caught all social medias in the original rule but catching it now is second best. That being said, I'm not sure we could have caught them all in the first rules anyway because of how she asked for them
