A customer service representative at Nintendo recently told me that a parent can't let their Nintendo Account be used by their child for online play without violating the Children's Online Privacy Protection Act of 1998 (COPPA) and that Nintendo can ban accounts for COPPA violations. A parent, he claimed, could only share their account with a child for offline play without violating COPPA.
I asked where within the Act such conduct is banned, and I was told I could find more information online. However, I thought that children under 13 can still legally give out personal information under COPPA so long as they have their parents' permission (although some sites like Facebook ban those under 13 simply to avoid having to deal with such issues).
Was the customer service representative correct in claiming that it violates COPPA for a parent to let their child use the parent's account for online gaming? What if the parent and child consent (which seems to be implied)? If this does violate COPPA, please show where within the Act it's banned.
