This Justin Beiber fan site has been penalized more than $100,000 for collecting emails of minors under 13 without parental permission. COPPA compliance is more important than ever. I find it ironic that kids under 13 aren't even supposed to be able to have emails in the first place on many websites.
"The details of the registration process varied depending on the site, so you'll want to read the complaint for the specifics. But the 25-words-or-less summary is that Artist Arena allegedly collected kids' names, addresses, email addresses, birthdates, gender and other info without properly notifying parents and getting their consent. According to the complaint, the company violated COPPA by knowingly registering over 25,000 kids under 13 and collected and maintained personal information from almost 75,000 other kids under 13 who started the sign-up process, but didn't finish it."
