Please do not be disrespectful toward others.
Separate the commenter from the comment.
Smart commenters still make dumb comments now and then. And vice versa.
Consequently, the "identity" of the commenter is not a reliable predictor of the quality of the comment.
Shared accounts such as this one can address this problem.
Each comment must stand on its own, apart from identity and historical karma.
