Is data available for closed competitions?

What is the DataDriven policy regarding availability of competition data sets after competitions close?

I am not able to find the data sets for closed competitions. Can these be made available? One of the stated purposes of DrivenData is to be an educational resource for data scientists. Winning code and reports are made available to learn from. However, learning from these great examples would be far more effective if the competition data sets were also made available. Without being able to examine the data, the code and report analyses have little meaning.

We don’t release the test sets, sorry.
