From my experience, vues are not only counted par the vues of the club's fans but also par the people who are not even users of this site. It counts how many people cliked on that link ou saw that content in the internet too.Perhaps, there are a lot of people out there who searched for images par using the key words that are used in that content .This is the reason every good user of fanpop tells others to use appropiate key words while uploading a content.
That's not strange at all. I've posté some of my photographie on a club, and it got way plus vues than the people in that club. When toi chercher on Google and etc, it brings up pictures from fanpop and people who aren't on Fanpop's vues are counted too. Plus people don't have to be a fan of the club to view it.
Since it's a One Direction image, no, there and tons, AND LITTERALLY TONS, people that are fans of one direction. So if someone google's one direction, and that image will come up, and they will look at it. So not strange at all.
