Going into that metaphore: Before we send people to prison we need a proper court of justice, instead of the police state we have now.
Agreed, we need some changes. Staff members should be taking care of proven scammers.
Locking them out of marketplace at least when there are multiple accusations from trusted members.
Rent hackers on tracking scammers worked out once 
That's very clever but hiring hackers instead of having mods actually do some work is not the way to deal with things.
just ranting that we need to educate people is plain wrong. the forum should also be active on scam reports or create a wide trust escrow service....
Amen.
