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.
They are not only used for illegal stuff but yes the majority of the time they are and that's why alot of undercover on those places aswell so always approach with caution. To make a dark marketplace it requires alot of effort and skill so I wouldn't just do it as a hobby project but really as something serious if you are serious about doing that.
well if some people are not going to make an illegal transaction in illegal marketplace then it should be considered as abnormal activity because if they're not selling illegal stuff then for what they're selling there? is there none better place? ,taking a risk that's not need is just plain stupid
