To see if the content on a website is modified regularly you should always check the dates appearing on it. Any change to the content, even a small one, should be registered under the 'last updated' tag. Sometimes it is difficult to find this tag, in that case check any of the entries made on the site. It can be a discussion thread, a status update or a new photo being posted. Check the dates beneath such posts to see when the last update had taken place.
