Jimbeetle - no I seemed to bypass both panda and penguin, it was only the latest algo that obliterated my non-EMD, old (frequently updated), and very best website.
Same thing happened to me...no problem with previous updates at all, but this one dropped traffic by 30%. I am now on page three and still dropping for searches I was in top 5 for at end of September. I can't see this as anything else other than a misguided algo penalty of some kind. I haven't gotten any warnings of spammy links at all, but I do have lots of dubious links to my images for example. I'm sure my main competitors do too, so I'm not rushing out to disavow all these links so quickly.
