This is true, too, but I meant users, too. It's all too common for users to screenshot things, etc. I see it a lot of the time on Twitter for example. You can delete tweets, but oftentimes it's pointless. But I also regularly see my gf taking photos with her phone of various apps she uses on her notebook, just to have the info around on her phone. I suspect it's pretty common, because it's much more low-tech then saving pages or API scraping.
