I have had mixed results with that as a user - sometimes I get to see a few pages of scroll before the nag screen to sign up.. sometimes it seemed timed instead, like not even second page scroll. Other times I was able to scroll through hundred on 'pins' before the sign up screen. I also remember times when I had three seconds to look at a screen and then most visuals are blocked by the sign up screen. Not sure if they are playing with this on a global scale or if my ublock and similar plugins affect it. The times when I could not see what I had expected - just an overlay nag screen, I certainly wish they were not in the results. Other times I found the curated visual content of pinterest to be better then google results or google image search. I had thought the big G algo already punished for showing full content to the crawler but blocked content to average web browser.. however I had the feeling some time ago that some manual tweaking on google's side and perhaps pin's side started affecting how all that was working together or not.
