Although I have no idea what the f this can be, I guess the cheat detection does not fail. That will be 64 for me
*** Edit ***
People might get my message wrong... I think anyone who ever played vs me knows I'm not using hacks during matches (just see my stats) or other online playing.
I tested a hack once to see if it works (It's senseless to upload something for the commitee to review if you are not sure about the functionality of it) and turned it in immediately afterwards. Strictly seen this is hacking as well.
The thing I don't know about is where those Arctic^ matches come up from, but the cheat detection will have a reason for this
