They do response to this, although it is not an inmediate response; I've submitted this kind of tickets myself before, having many, but not all of them replied. One of them was about this very same issue, which I sent about a year ago. EB answer was that this violation code was a hack.
I've spoken with Vermillion about this issue, since we're working as staffs at the same website (though in different areas, he's currently the senior anti-cheat staff for CoD @ One.cl and I'm currently a major administrator) and having seen so many cheaters before (I also worked in Vermillion's current possition) and not existing any reference about any false positives at all, this is a hack, in my opinion. I'm sticking to that old reference.
I too have submitted a ticket regarding this issue and will report about it as soon as I get the response. It's useful for us all to have updated information regarding this violation, to ensure the accused players a proper and just "trial".
