Banned? Um, what? I did this puzzle last night and I haven’t been banned. I consistently fell through the platform and died and had to restart the puzzle each time. But I wasn’t banned.

I did this puzzle 2 times on this week and i fell several times. Sometimes, i was transported to the golem, but sometimes i fell all the way down to the ground and consequently died. However, i haven’t been banned for this also.
Perhaps those guys were banned for another reason
