A large number of HYIP websites do not resolve after some time

It appears that most of HYIP websites are using scripts, or modifications of the same script
It is observed that though the HYIP websites are advertised extensively, many of the HYIP websites do not resolve after some time.
ai-startup.cc is one of the most famous recent HYIps which did not resolve, despite having 12506+ investors
rub-invest.pro is another HYIP which does not resolve.
It would be interesting to find out the real reason why the HYIPs do not resolve, whether they have webhosting , domain registrar or other problems.
