in my opinion skeet free can be an actual thing, theres just no point of releasing it to the public(atleast for now). there were some rumors going around abt nl beta users being banned from gs, so the drama was already here for a while. keep in mind that anarch1st47 is an unknowncheats mod so he for sure have some knowledge in this field, and with help from other skilled people involved with neverlose it is really possible that they freeed skeet.
gamesense is just like any other cheat, nothing is uncrackable so dont glorify it like that, time will tell if its real or not we just have to wait for now.
