Generally any contact like that would be considered corruption of a minor. Feel free to contact your local Children's Services Bureau or whatever it's called; these are usually administered by the county for placing children into foster and adoption homes, and as well for managing child support payments, among other family-law related matters. Find their email and use a throwaway email account on hotmail or something. It can't hurt to simply ASK.
Since I have some contact with foster care families, THAT is how I know that. At least, that's where I would start.
Also, remember: "Consensual" often doesn't count at all with a child. That's why society defined the age of majority.
