What happens to all the threads that are taken down to be looked at behind the scenes?

I see loads of threads that go poof for this reason, but I've seen many deleted for being a PBP, etc. so you know they're not that, yeah? I've then seen threads that are kept up because nothing looks suspicious behind the scenes, but they were never taken down to look?

Just curious?

there's a parallel MN, a vortex where all the juicy stuff goes.

I often think it's just to stop people keep reporting the thread
