The thing that sucks is we can't even know for sure if a service is going to end up being a scam. We liked ChipMixer due to their reputation and long-running service but who would've know if they end up wanting to scam anyway.
We did not heard that Chipmixer scanner anyone, what happened was that the site was taken down by the government becuase the mixin site was linked to mixing of illegal coins. But that Chipmixer was linked to scamming its customers, there is nothing like that. Whirlwind is nothing but directly scammed its customers.
