We all know about hacks, scams, password leaks and all the shit that's happening in the crypto world and we also see lots of scammers using mixers to eradicate the possibility of them being caught at all (though there are traces, but using mixer saves these scammers at the least, not intentionally but being unknown to the source where the coins came from).

Now, let's say that a hack happened some day at some exchange for about $300 million (or even $3 million, just e.g.), and the exchange immediately opens up about the hack. For a second, just think that the scammer keeps the coins in his wallet and doesn't move them for some time, however FBI and other major authorities are aware of this hack and they give orders to mixers that if a specific address is provided to the mixers (if they know exactly on which address the hacker has kept the coins), and they ask them to immediately report them about the same, then let me ask some questions:

1. Do mixers know where they're getting a deposit from?
2. If yes, will they co-operate here with the officials and let them know about the deposit?
3. If they do, how will they stop the scammer from moving his funds out of their mixer?
