Really, the corruption in south america generate several cases in privacy break. They've spied my downloads and charged based o copyright. I've been using Mega but there's limited monthly bandwidth >.<
That is not "spying" that is monitoring for illegal downloads of music/movies/etc.. and is done normally. It's not because of corruption and is not done by the government although it should be done with approval from the government. If you put a copy of your own files on the server I am sure you won't have any issues. The ISP is just told to search for illegal downloads and files and report it to the authorities. If you have a document on your computer that states "I don't like my mayor he should be fired" and they bring you in for being a dissident, that would be spying on you.
