Many website owners blame the existence of a Google Sandbox effect for the struggle or the failure to make an impact in search engine results, even though their intensive optimization activity. Despite the fact that more and more people seem to believe that this Google Sandbox effect is real, this couldn't yet be proven, it still remains a myth, a legend. It is very difficult, even impossible, to measure the Sandbox effect in a scientific manner, through experiment, and to observe it. This means that until the day when this mystery can be solved (it wouldn't be too soon) we can only add hypothesis regarding Google Sandbox to the ones already existing and speculate around them, but we can't really verify any of them.

Till someones solves the mystery about Google sandbox they will update it again. This is just similar to changes in search ranking algorithm and aims to eliminate black hat methods.
