You are right that laws aren't enough. It's the same situation with a school bully. You can complain to the teacher about it and they will make them stop. Often

You are right that laws aren't enough. It's the same situation with a school bully. You can complain to the teacher about it and they will make them stop. Often the bully will then recruit other kids to bully you because you are a "snitch" or teachers pet. Similar to the whole blacklisting issue. That person stopped my illegal behavior so I'll show them etc. What we have to fix is the idea that because someone undertook an enforcement action that they are a risk. If your company treats it's people fairly, you generally have nothing to worry about. If when presented with blacklist info people reported it (especially when it is illegal) the culture around this would improve.
