I think in Italy the first who made something like this was PeppeSess of Fenix Development team. He decided to not sell it. Now everyone make something like in new or rebuilded server. I make mine too, just some lines of code and a better HTML of this one. What make really the difference is how it is coded and integrated in a GM, can’t be really standalone. I can just say, be careful from who buy things, because is really easy be scammed from who have not a good support. I see in hacker selection 3x SIM CARD, wich phone grant use of SIM CARD today?
spoiler: Peppsess never made anything but always paid the developer to make the resources he sold. The resource these people are selling has been stolen (from me).
