I heard about a guy getting hellbanned for flagging all but one of the "Steve Jobs is dead" stories on the day Steve Jobs died. Each time my finger hovers over the "flag" button I wonder ". . . is this really worth the hassle?" Then I close the tab and go off somewhere else.
(I've flagged probably 10 things total.)
EDIT: jlgreco corrects me. The guy I was thinking of was flag-banned, not hell-banned.
