Whether that's true or not, you (i.e. everyone here) need to follow the rules whether someone else is breaking them or not. Any other approach guarantees a downward spiral, because it always feels like the other person started it and did worse. To put it in terms that many will remember from their mothers: two wrongs don't make a right.
Perhaps you don't the article author (or whoever the other person may be) any better, but you owe this community better if you're participating in it.
