No one will try to make a list scammers/scam websites because even a website is taken down it's easy to make a new website like what cloud mining sites and will operate again and again. If you see some list I bet it's not updated and not all scam sites are listed there.
Indeed, there are so many reported scam sites, but mostly discussed in a thread and then vanish.
Maybe some people have ever tried to make a list of scam sites but it's worthless as it's not easy to maintain a list with so many scam sites around which easily created everyday, if you make one, it will be contain tons of scam sites. Moreover, it's easier to use google and check whether a site is legit or shady by read some reviews about it services.
