You know, there is no such thing as a "Pinterest" recipe - Pinterest is just a place to visually store links to other websites.
That being said, I love Pinterest for organizing my recipe ideas. I do actually make a lot of the recipes I find, and then recategorize them into ones I love, like, are okay, or hate. I do thoroughly investigate each pin to make sure it links to an actual recipe (not just a picture!), uses ingredients I'm willing to purchase, and takes a reasonable amount of time. It's been a great tool for me over the last few years. Most of my pins come from Googling recipe/ingredients outside of Pinterest.
I have noticed that many of my friends seem to pin indiscriminately, though...
And leave other people's weird descriptions on pins when it doesn't apply to them...
