Thanks for your concern Steammaster, but unless someone from the hacker group "Anonymous" wants to take this project on, there is no way to stop the pirating of Machinarium. Amanita Design is committed to releasing
DRM free games so, subsequently, there's no concrete way to prevent pirating.
However, it's worth mentioning here that back in the summer of 2010 Amanita Design offered a
Pirate Amnesty and - surprise! surprise! - LOTS of pirates came on board and finally bought Machinarium.
So there is still hope for our mongrel species after all!
Happy
Christmahanakwanzika!
