This question already has an answer here:
Recently, when a user deleted his account on Lifehacks, his questions with negative scores and no accepted answers were deleted, including this feature request. However, some users thought that this question was useful, and started a (successful) motion to undelete it.
I don't think it should have been deleted -- yes, the question had a negative score, no there wasn't an accepted answer....but there was an answer with a positive score. Why should positive score answers be deleted, ever?
Please protect positive score answers to deleted users' negative score questions from damaging deletion by the Roomba.
