There would be a huge list of such projects if we start numbering those. There already have been a lot of scam projects busted by some of the reputable members of the forum and also you could find list of their individual busted projects which would perhaps save your time to hunt those yourself.

ICO and IEO industries have given birth to a lot of scam projects and some of those were also successful to collect funds from the investors and vanish forever. This has made a lot of investors stand on a verge of loss but the markets might change in the coming times with more advanced features which would never allow anyone to develop a scam project anymore. I even feel some potential projects might be scam as we would never be aware about the actual team behind those.
