OK, let me rephrase.
The DBA is not responsible for the *content* of the data.
The DBA *is* responsible for the safety, recoverability
and integrity ( where possible ) of the data. The DBA
is ont resposible for the data's content, except where
the DBA is responsible for constraints that place some
controls on the data content.
If one of the developers enters incorrect data into
an application, and then wants to know why the database
is broken, I will tactfully ( maybe ) inform him/her of
the error in his/her ways, and will help that person
correct the problem.
Do I get to swing the club? ;)
