I found a new role for downvoting!
My criteria for downvoting us pretty narrow, but I've expanded it a little: whenever I try to keep him honest by commenting on his posts, and the snowflake deletes my comment [i]and[/i] somehow manages to remove the "[i]this comment has been deleted by the author of the main post[/i]" scar were my comment used to be, I'm downvoting the post!
