To be on the safe side, do not play/log in at all until the FM ends that is until Nov 3rd 7pm UTC. They have the event countdown on Reddit if you want to be sure.
A reminder, avoid using this modded version over the original during Full Marks or House Pride. Friend of mine reported a dude with over 10k points during FM and JC answered back saying they detected 6 other people using hacks and were banned.
Even if your with low scores during those events, JC will run a background check on everyone on the group regardless of the reported target. Just avoid playing the modded apk while those events are live and you will be fine. And if you do decide to play on those events, then at least be smart about it, if you blow your cover,chances are your gonna be banned alongside with someone else.
