Any person who hides their Identity using Network Solutions will always have those information actually but its interesting both ethereum cash and dark uses Network Solutions. Looks like he still wants to save some bucks even when he scammed thousands from investors. If he use some other hosting provider, it might have been not suspicious enough. Almost 99% only same developer created these two tokens.
as much as i have heard, there had been few other failed projects related to these dev, which made a fight and seems to stopped for a while
but recently have heard they are working on different projects each one (not confirmed yet)
hope they wont success in scamming again
