Facebook, cellphones, or any other form of social media are not allowed at robotics competitions or practices.

Other than than, it's up to the parents to govern it. What the kids do on their free time outside robotics doesn't fall under the purview of robotics, unless it directly is about robotics (i.e., they call a mentor a name, etc.)

Disallowing private conversation seems pretty silly. You'd be creating an un-enforceable rule just to try to remove some liability from the team. Private conversations are also necessary sometimes. Why try to extend robotics beyond what it's meant to be?
