Okay, so only one out of about 10 websites of mine actually dropped insane rank positions, and guess what? Only one inner page on said site dropped, and that inner-page had a 301 pointed at it. To me, this has to do with 301s. Not all of them maybe, but still.
And about it being affiliate sites getting hit: Couldn't be further from the truth in my case.
@Renfield-Files - You're in the adult niche + SEO, right? Seen any crazy changes?
Me and many others don't use 301s and got hit just the same.
