Three things can not hide for long: the moon, the sun and the truth

This is the slogan of Wikileaks a website under construction that

is developing an uncensorable Wikipedia for untraceable mass document leaking and analysis. Our primary interests are oppressive regimes […]. We aim for maximum political impact; this means our interface is identical to Wikipedia and usable by non-technical people.

We also have some experience in science with whistleblowers leading to further investigations. How will this site guarantee the correctness of any information?
