Plus there may be absolutely nothing wrong with the site whatsoever but, unfortunately, the algo/Panda/Penguin erroneously considers the site a target and whoosh, it's toast.
For example I have a site which for one keyword the Panda demoted it to oblivion in Google.com, it is the US spelling of the keyword. In every other Google SERP I am #1 or 2 for this word and for the UK spelling of it I am at #1 or 2 even in Google.com.
Stupid or what?
