I flagged a answer in [this question](https://askubuntu.com/questions/965145/e-sub-process-usr-bin-dpkg-returned-an-error-code-1-mysql-install-ubuntu/1006680#1006680) As "In need of moderator attention" on a answer that was:

 `sudo rm -rf /var/lib/mysql` 

My flag was declined, perhaps because I was not specific enough. I did not think an evil answer such as this would need much more explanation.

How should I have flagged the answer?
