I believe data explorer is enabling users to get around restrictions, as with a simple query, users with less than 1000 rep can get vote counts(the ones unlocked by Trusted User), (see this query), as well as many kinds of votes or possibly even flags(line 4 on this query, or even that number changed to get scarier vote statistics). I believe that the system should be revised denying access to sensitive data to users that don't have sufficient rep on the site they are looking at.
