Fake project is really frustrating if you're one of the victim especially for investors and bounty hunters.
I had read an interesting way to make sure the project is real. You can identify the project is fake by it's address of the company who is running IEO/ICO. Fake project would be indentify with this way because they put fake location. You can check it with google maps to verify if it's real.
So how do you indentify if the project is fake?
Hhmmm...identifying fake projects!!! Well, the issue is that, there are some red flags that are glaring pointing to a particular project to be fake. However, there are some fake projects that were well packaged in such a way you could not even discover at all. For example, on the issue of address you mention, fake projects can have real address. We can only try our best to do findings and stare clear of the glaring red flags, but you cannot totally discover or run away from all fake projects.
