Okay as you see that Panda is affecting low quality websites with poor English grammar and tenses fault. Even 3 of my websites with a poor content quality ( Spun articles ) got hit by Panda, I didn't use TheBestSpinner how-ever but some other mix of spinners available. So I actually want to see how good is TheBestSpinner based on how Panda hits the websites ? Of course no one can guarantee 100% quality, some manual checks are always required but the manual checks shouldn't be some kind of complete article rewriting. Maybe we can put a Spun article into some tenses corrector ( Like Microsoft Word ) or any other known to other people. So how do you see it ?
