There are a slew of kids their age posting inappropriate pictures, doing inappropriate things, fighting, having sex, etc and are overall much worse than Willow and Jaden, and CPS isn't involved.
Nothing will come of this. They seem brighter than the average 13 year old and 15 year old, and I honestly do not see them doing anything worse than other kids their age.
CPS's involvement is taking it too far, especially since they aren't going to do anything or make anything happen anyway except traumatize the kids. Sometimes they do more harm than good.
