Does unity asset store team review assets to make sure there is no illegal content/data transfer code

Well, this is what I could find in the submission guidelines for the Unity asset store:

After the submission, Unity’s Asset Store Team will review your package. We will make sure that you have complied with the basic requirements: is the preview data ok, is there any documentation included and does the demo scenes play as intended and so on. We will also assess the quality of your asset, and if necessary, give you feedback about possible bugs in your code or quality issues in your 3Dmodels.

So ye... not sure ;)

But I think this question might be better suited for the forums as it is more likely that people who actually know the answer to this question are on the asset store forums :p (Or read the 'other question' part of the submission guidelines and mail them)
