Tons of fake currency found it's way to india ,perhaps maximum to keala and bought land?

Tons of fake currency found it's way to india and perhaps maximum to kerala .Utilized this fake currency to buy landed property by paying much higher than any body else could afford .This caused certain community to own majority of land every where and continue to do the same .Unless it is checked immediately it will be the biggest injustice and crime to indian public.What action government taking to trace back all the transaction taken place at least for the last 15 years to give justice to the common man and to india .All such properties should be confied .What is your opinion ?
