This particular operation seemed to be in Germany - we're in another European country. She got two notices and ignored both. Nothing has come of them so far. Whatever about tweeting an infringing image, retweeting it seems like a bit of a reach.

I suspect a lot of images on Twitter are unintentionally infringing, and that Twitter users typically remain ignorant, because not many are targeted for enforcement. If copyright enforcement against tweeted images takes off, maybe that will change.

However, doesn't Twitter itself add images in some cases (especially where a user tweet a link, but probably also retweets of an image)? If Twitter still does that, does it suggest Twitter itself isn't being targeted for enforcement? If so, is that only because enforcers prefer smaller prey?

Anyway, best of luck to you and your wife!
