"For how much money heroes and legends are willing to advertise fraud and scam?"
Interesting question if we consider the recent case of Sinbad.io. Next mixer will pop up and get advertised again by heroes and legends .
Now the question I did put or throw back at you would be, was sinbad mixer a scam before it was seized by the government?
Yes!
For anyone doing at least basic research about Sinbad.io, it's been easy to spot how fraudulent Sinbad.io was: Sinbad.io was a re-launch of Blender, a famous mixer operated by criminals: Crypto mixer Blender has been rebranded to Sinbad, says Elliptic:

For Sindbad.io = operators wanted to wash own coins from crimes and hacks, get clean funds from Bitcointalk for mixing.
Sindbad.io operators abused Bitcointalk to have fresh funds for mixing.
Sindbad.io operators are SCUM!
