COPPA Steps on ICQ Privacy

An AC writes "According to this CNET news.com article, AOL has started to remove ICQ accounts of anyone whose info states that they are under 13 years old to comply with the new Children's Online Privacy Protection Act (COPPA) Yahoo is now reportedly asking customers to provide credit card numbers to verify that they older than 13! Now, I am all for protecting kids online, but isn't this a bit over the line?"
