Many times I've been looking for some obscure part that I would like to purchase, only to find search results flooded with pinterest images of it that are utterly useless-- they don't even tell me what the part is called, and certainly don't let me find where the image came from.
If pinterest was using a GAN to generate plausible random images would we even know?
We could both be completely right about our own experiences.
It makes sense too that if Pinterest is promoted hard enough to get an 'adequate' dosage to everyone, that some people are going to be overdosed really hard even before you begin to factor in differences in tolerance.
I routinely search with site filtering to eliminate it, but every time I forget it's like stubbing my toe and I feel dumb for forgetting the 19 character magic word required to get useful results. Doubly so because I often misspell it.
If the web were my shell I would have punched in "alias gis=..." long ago.
If you are searching for something and find a link to pinterest and click on it ... then what? You see a bunch of images of the thing you are looking for: no article on bobcats, no way to buy "winter running shoes", no way to buy that book, ...
Maybe you can filter out those results by domain? It would be nice if you could just add it as a setting, though.
