It was a very strange thread, but I agree that context might make a huge difference to understanding of it. If it happened soon after the Green Trouser Suit debacle, I was taking a break from GN at the time, as I found the atmosphere then very stressful. It may be, therefore, that some of the peculiarities of the thread (white socks??) refer to things going on at the time.
If that was why GSM was banned, there must have been something in the water, as whilst it was all very tetchy I have seen a lot worse on here. Or maybe, as Casdon suggests, it was a case of straws and camels' backs. I don't think Matilda May has been seen much since though 🤔
