IANAL, but my understanding is that nothing in COPPA prevents children under 13 from making accounts or using Internet services. If this were true, Roblox would not exist. COPPA only limits collection of children's personal information. A company that says COPPA prevents them from allowing children to use their services really just doesn't want to go through the effort of not collecting that personal information. So, instead they throw up their hands and just blanket forbid children under 13 from signing up, to avoid having to comply with the law. But, this is their own policy, not anything mandated by COPPA.
