Yet they are affected and kicked by panda. This is due to the reason that facts you’ve read about Google panda are not accurate.Yes, I am 100% correct about this fact because most of the people who have been hurt have good original content. This due to the fact that there has been any search bot developed in the world, which could works as an artificial intelligence agent and imitate human beings with cent-percent accuracy. So I am sure that in any of the way possible, Google bot cannot judge quality of content because a piece of content might look spam to me but good for soemone who was searching for it.

The reason is that there some scrapper sites which tends to take a copy whole of your content or even a part of it.

So I would suggest you to make a deep search about your content (even though, you’re sure that you haven’t copied) just to make sure that others have not copied it. You can take help DMCA in taking down such content.
Also Panda powered Google bot can calculate the keyword density. So if your articles are center around som keywords, then this might be a reason behind your suffering. It has also been seen that changing niche has caused some problems to sites.
Panda understands English well. It works like program in Word Editor which underlines grammatical errors and spelling mistakes.
