"However I've probably bought more stuff as a direct result of ad exposure on Instagram (3 things in three years) than in the entirety of the 25 years I've been on the internet."
Could you specifically describe the ads and the products involved ? I am very curious and would love to have a sense of what they succeeded with (for you).
I have been of the mind that targeted ads are terrible and that ad firms and ad-tech firms and (that entire ecosystem) are fleecing the ad buyers who will eventually wake up to that fact...
It's 2019 and if I search for "volkswagen emissions scandal" I will get banner ads for new volkswagen cars. For a week.
Or, I would, if ublock origin was disabled ...
