I would say this debate is not haw many, but more, what defines a moon.
Saturn only has about 18 moons.
The rest are just small chunks of rock not worthy of the title "moon"( In my opinion). They keep adding more because detecting technology is getting better and we can see smaller and smaller objects. When will it end?
Anyways, pehaps their title of "moon" is deserved as they are actually useful to Saturn in one way. Most of these asteroid-moons are called shephard moons. The shephard moons are largely responsible for Saturn's beautiful ring system. The moons do exactly what their naem suggests, guide the rings of Saturn (billions of small chunks of rock) into paths as well as help make them hold their shape.
Back to the problem. When will it end? I say there should be a limit on what defines a moon, possibly some sort of mathematical equation, or just a fixed number on the minimum requirements of a moon. I vote less that 33 because I believe the hit the number of moons Saturn has now and are just wasting time naming small asteroids that just so happen to be orbiting Saturn.
