So the best thing we can do is to report those scam sites under their control and hopefully within 2-3 days, they will shut it down for good.
If you have to report this is with many people so that the report is widely responded by the domain at least there are no victims in the promoted ponzi scheme because ordinary people will always be attracted to high returns.
Ponzi schemes come almost every day, and never die unless we already know, so we must be able to avoid it while reporting the site.
