Only exception, which was what happened to you is when you're provisional. After 20 games rating can't go down with a win, before that it can. Read the FAQ.
Well, I am pretty perturbed with a game where - at the start of the game - my opponent was in the 1700s and now my opponent is in the 1300s!!!??? Talk about a psychological play!
