You can flag and should flag the post for moderator attention, pointing out the plagiarism (which in this case is small, but it could be a sign of more endemic copying behaviour). I agree the post is a straight copy (down to the error that Soner edited out).
The retaliation you received is not normal behaviour either. With only 3 downvotes, it may slip by the serial-vote detection. If the votes have indeed not been reverted by tomorrow, ask a moderator to look into it.
