User blog:Vixenblaze/COPPA?

I have a question about COPPA. (in no way does this example protain to me I am merely curious) What if a user made a wikia account when they were underage? But, they didn't get caught for being underage and/ or lied about their age all the way up until they were 13 in real life. Would they be riticuled for their COPPA violation even though they are now of age or would no actions be taken? Thanks :3 -Vixy
