Actualy you can see some of it at investor based games https://bitcointalk.org/index.php?board=207.0. Some bad sites here are bitcoin doublers and some coinmixing service. Also some cloud mining and investment sites.
Bethenext.io
Twinbit.info
Coinn.io and many more. These are bad sites which very obvious because they offers higher than normal rate and too good to be true.
