Astonishing if true: "only 15% of Crimeans voted for annexation"

Forbes is reporting that the "President of Russia’s Council on Civil Society and Human Rights" has accidentally leaked the true figures for the Crimean referendum:

The website of the “President of Russia’s Council on Civil Society and Human Rights” posted a blog that was quickly taken down as if it were toxic radioactive waste. According to the Council’s report about the March referendum to annex Crimea, the turnout was a maximum 30%. And of these, only half voted for annexation – meaning only 15 percent of Crimean citizens voted for annexation.

          [...]

To make sure no one misses this: 

Official Kremlin results: 97% for annexation, turnout 83 percent, and percent of Crimeans voting in favor 82%. 

President’s Human Rights Council results: 50% for annexation, turnout 30%, percent of Crimeans voting in favor 15%.
