Copyscape or Plagiarism Tool?

I have bought a lot web 2.0s from a BHW seller, he claim that all contents are handwritten, so today i checked the contents with copyscape and it appears no results which mean its not copied but when i check using plagiarism tool, all contents did not pass at all.

Why? and so how, all web 2.0 are Tier 1 to my money site, will this make my money site get penalize?
