... v[a]na haec more famae credentium otio a[u]gebantur; ceterum libertus...

The next phrase is "credentium otio," which Furneaux describes as those who are too lazy to distinguish truth from falsehood; it can also mean those who have nothing better to do than circulate rumor. Here "otium," which can mean "leisure, retirement, peace," has a pejorative meaning "idleness."
