Natural bodybuilders 100% go through bulking and cutting cycles.
Outside of noob gains it is incredibly difficult for a natural to add muscle mass when in a calorie deficit and recomposition at maintenance calories is also inefficient in the vast majority of cases.
They won't bulk the same way someone on gear does, but it's still the most efficient way to add muscle mass in the vast majority of cases.

No, they don't. They simply eat enough to continue muscle growth and attempt to shed fat before a competition. Any non-competitor doing this is just engaging in quasi-religious nonsense or rationalizing a bad diet.
Bulking and cutting have meaning, and we're not going to turn it into any caloric surplus vs deficit.
