I agree with your point, but technically it is not always easy to know whether someone is a newbie.

Usually one does not check the guy's personal node before vote, even you check, a new user of this site is not neccessary to be a newbie.

Maybe you can judge this by the content of the post, but I suppose that is not always straight forward ;-)

But I agree with your point. Look at this deeper, people come here ask for help, not come here to ask you to judge them.
