"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 .
Well even if they did pop up here the people who post them and also advertise them would be dealt with given that theymos has now banned them and issued a pre-emptive warning to those that do:
https://bitcointalk.org/index.php?topic=5476162.0Even like the Dutch Law Enforcement recently said about the Sinbad seizure, mixers aren't inherently illegal so most won't or shouldn't have a moral issue with them but there are always people willing to compromise their morals if they're paid to do so, but morality isn't always a black and white thing either. Some people find alcohol, gambling, sex and sex work immoral whilst others don't.
