I was reading when that forum started going down the drain.
It started with one or two of the slightly older users (I think our @anon85728687 was one of them) complaining in the chris skinner thread, that that thread had been spun off into its own thread.
Those one or two posts (I genuinely can’t remember anymore, but it certainly wasn’t “loads” as Feathers suggested) were deleted and the thread locked within minutes. (I assume that was always the intention behind spinning it off? bait people into complaining, thus giving an excuse to lock it.)
Shortly afterwards someone (AFAIK not the same people, but who knows - this went so quickly I could barely recognise anyone, but none of the avatars involved looked familiar) started spamming in age old threads on unprecedented levels. It was quite impressive, really, the level of dedication that went into it.
