I will definitely check the link you provided to verify if it will work for me. It is important to expose the scammers by using all means to foil their tactics. Scammers register many domains using one ip, so it would be good if you can verify it more easily using this method.
I do this daily for more than a year, use their ip and use reverse ip, really helpful. All the links from the ip I posted, work more than decent. You don't have to verify anything, they are all scams. You can also use hyip monitors to copy the random investment texts they are using.
