Witnessed these happenings first hand, and iEvolive was sold one of these heads for 60k, can also vouch that these are real heads.

 

A fact which I resent, but yes.

 

I've looked through the mcmmo code and it's an intended feature on McMMO's end, but it wasn't known on ecc.

Now it's up to andrewkm , he has to choose whether to keep it in-game or not. (Note, the whole SHAKE feature, because you can't simply remove the heads)
