i think that they create these websites same as normal ones, just main difference is that they sell illegal stuff there, but i am sure that there is tutorial for that
Dark marketplaces are very bad. There are indeed a lot of scammers and you can buy some illegal stuff and that is not good. But you cant stop people to not using that and that is the problem but try as much you can. you do that.
Yeah that's right no doubt, we should avoid such marketplaces, as it will be a regretting moment if you keep on using it because if you are once caught using(buying stuffs from their) it then it will be very bad !
