For me
- shopping on crappy discounters
- listening to podcasts
- literally every step in a city
Nothing digital shows me ads, but going to a crappy supermarket is crazy. Most organic stores dont have any ads, its really disturbing to be in others. (But the fact that they are not able to feed humanity is a complex issue)

You need to use a hardened browser with as little unique identifiers as possible. Then you need to delete cookies and use different or unified IP addresses, obviously.
