I thought they were closing due to internal problems nothing to do with Hasbro. As it has already been said, Hasbro is not ignorant of KOToys and other websites promoting KOs, they just choose to do nothing about it.
Maybe the phone call had nothing to do with it. However there was some other information I found and provided them with (which I have since edited to remove) which would have made taking them down dead easy for Hasbro to do.
