Unfortunately, one of the targeted domains, mooo.com, belonged to the DNS provider FreeDNS, and as result, 84,000 websites were mistakenly taken down. These sites saw the following message on their website, according to TorrentFreak: "Advertisement, distribution, transportation, receipt, and possession of child pornography constitute federal crimes that carry penalties for first time offenders of up to 30 years in federal prison, a $250,000 fine, forfeiture and restitution." The FreeDNS owner quickly released the following statement on their website: "Freedns.afraid.org has never allowed this type of abuse of its DNS service. We are working to get the issue sorted as quickly as possible."
This happened on Friday, and on Sunday the domain seizure was reverted. The subdomains slowly started to point to the old sites again instead of the accusatory banner, but since the DNS entries had to propagate, it took up to three more days before the images disappeared everywhere.
