It's interesting how this keep happening when it is so easy to do it right. In my case someone commented on my flickr that a startup was using one of my photos without attribution, but it only took one email and the CEO/founder immediately responded apologizing. Other times I've got emails asking me if it was OK to use a photo, as if they had to seek permission. I wonder if the problem is the need for more education/outreach to explain CC?
