I was just reviewing late answers when this post from this user was brought to my attention.
At first it thought there is just a problem with his full-quote of the question. Then I saw that he copy/pasted also the first highest-voting answer and didn't provide any new thing by his own. Then I checked his profile and found that he posted two other similar 'useful' answers on two other question.
I feel some action from a moderator is needed in this case :-/
EDIT: Apparently a moderator took care of it. A note from whom ever took action would have been nice.
