In 2015, I was lucky enough to be sued by them for infringement of pictures. Our website is APP recommendation website, and we grab data from Appstore. One of the APP's cover pictures uses infringing pictures. If APP is A and Appstore is B, our unlucky C has also become a defendant. Although we have helped by a professional lawyer team of Baidu, we finally lost money, which seems to be 2000 yuan one picture.
