"On October 9th the second episode of Oreimo was downloaded from Anime News Network's contracted content delivery network when security measures believed to be in place on our video server failed and were unlawfully circumvented. Anime News Network assumes all responsibility for these failures and emphatically confirms that Aniplex and its partners in Japan were in no way responsible for this occurrence.
Anime News Network would like to apologize to all of the fans of Oreimo in North America and Japan for the disappointment caused by this unfortunate situation.
As of this time all simulcasting on Anime News Network Oreimo and togainu no chi ~Bloody Curs~ will be suspended indefinitely while we continue to investigate this breach and correct the security lapses that allowed it to occur. At this time it remains unclear if, or when the simulcasts will resume. Anime News Network will issue a full refund to all our members that purchased a premium streaming account for Oreimo or togainu no chi ~Bloody Curs~."
This also means that both Oreimo and Bloody Curs' simulcast have been suspended indefinitely :-(
There's not word yet over if ANN will simulcast series in the future due to this incident.
