Yesterday I got two separate accounts of defamation against me.

The first one Find the rotation point of a sorted array that is "rotated" accused me of using multiple accounts to down-vote their question after a comment I had made:

You are not sure #1 yields correct results all the time, and you know that #2 definately is bugged, and you don't inform us what the bug is .. What exactly are you asking then?

The second Checking if a directory exists in FTP without relying on exception handling accused me of using shadow accounts to garner points on a question I should have left alone because it was and old question.

I find defamation unacceptable. I flagged both users. However, is this the way we should handle such behavior? Just flagging the comments and moving on..

I would like to know the site-policy for demafation.
