Pretty sure you misunderstood. He's saying that if you cancel your sub AND you have compensation days for downtime, you still lose your slot but are able to redeem your compensation time. There's still only 100 slots, but there may be more than 100 people using the cheat at the same time if you cancel your sub, then activate your compensation days at a later time. You can't expect him to not sell another slot after you cancel your subscription.
@Zlitz only question I have, is let's say the cheat is never ready for release, ie. you guys are unable to ensure it stays undetected or whatever. How will the users be compensated? I mean, we're going on 2 months here paying a hefty amount for something we can't use.
