We would be happy to see no one else getting scammed neither, but HOW?!
By simply controlling the greed of grabbing any thing that look like free/easy money
Why won't we collectively contact the domain/registrar where he creates all these scam sites and get him arrested once and for all?!
How Domain registrar is in fault ? Did you checked that business was registered or not? Did business looked legit? Did business model was sustainable?
if answer to any one of question is "
NO" then do not deal with it.
