I requested a reconsideration request for a deindexed site of mine. G answer was " bla bla bla bla bla bla quality guidelines bla bla bla quality guidelines". Then I checked my site with copyscape and it appeared that there are some duplicated content on other sites. But it is duplicated back in the time so until the penalty it seems it was not a big problem. So my question now is - is it now this content problem and because of this G team rejected my request ?
