My Friends List - Half at 0 Trophies - What's up with that?

I recently noticed my Friends List has half of my friends with 0 trophies. Does anyone know the cause of this? There’s about 20 at zero. I find it hard to believe they all cheated. Could it be from inactivity? Inquiring minds want to know.
