scrapped content identification methods

Hii friends,

was wondering does any one knows how ad networks like adsense,ezoic,mediavine check for scrapped content in a site ( the methods or softwares they use)

I assume experts in BHW must be having reliable information in this gathered through current or ex employees of those places.

And may be ex employees of those places might be in this forum too .

A simple Google search of random sentences?
If softwares could find them, Google would be the first to implement
