Some hoax sites do not have enough money to pay for an easy URL, and need to upload their site through a free webserver, such as geocities. One way of making sure that information found on the internet is true is simply looking for different versions of the information. If most websites say the same about it, it should be true. Other hoaxsites are quite stupid, others are sites for paranoids, like the one selling Aluminion Foil Deflecting Beanies. If you know what you are looking for before entering a website, you will avoid hoax sites.
For example, if you are looking for the Dreamweaver Studios website, and you enter the hoax one, you will know that it is a hoax. Most people know that dreamweaver studios does not sell the moon.
Another way of avoiding hoaxes is simply looking at adverts. Dreamweaver holds adverts in some magazines. If you look at it, it should say what the official website is.
