If u run wordpress . there is a plugin for wp and all articles pass the copyscape even if they are very very Copy/paste articles more details , pm .
Well, your articles won't be readable then. After all, you "write" them for SE, not users. Also, this is a solution for very short period. Your blog will get banned sooner or later. How about writing unique articles?
They are readable. Google responds good at this , is a plus not a minus . Think that you have a blog with automatic posts ... with this plugin will get loads of traffic because google reponds very very good.
I looked at a plugin of this nature recently and it produced poor output. Just write your own, and if you cannot then pay someone else to do it
