Actually this had been around for so long and I think it is not only with that site, there is also a site with csgo it is about bitcoin too using that same script. You can not say it is a scam until you tested it actually. I came across it but didn't tested it just because it is an illegal way of making money even though it is working. With that process you can be making more than 1000$ a day. It is illegally don't get greedy to try it and it might turn out to be a scam too.
You will not make ANY money with this, illegally or not, because I actually have tested it, without buying anything.
When you input the script that "changes the timezone," it will always be the same address, which concludes that it's a scam.
If the timezone is actually changing, why would it be changed to the same address every time?
Don't fall for this.
