I did warm calling for SP Ausnet, back when they were installing smart meters. Boy oh boy, the amount of drivel I heard about the "dangers of 5G". Literally had one guy threaten to shoot our tech and myself. (I got him a police escort instead haha).
In my experience it's almost always the people who smoke 2 packs a day, drink more booze than I thought a bottle shop could stock, and drive at 30km/h over the limit at all times that'll bitch about 5G causing them brain damage, or COVID vaccines being microchips or whatever the latest conspiracy is
