If I see something that is blatantly wrong I'll typically say something like I'm surprised nobody has flagged this yet and tell them why to give them the benefit of doubt and opportunity to correct it on the next one . I have flagged a few repeat offenders though. But heck even I was hit with the cheeta bot had a friend send me a joke I though was funny so I shared it hear and boom apparently it was a copy and paste from some joke site, live and learn
