Quote from mycryptomixer

"For example, if you happen to withdraw funds through a Bitcoin exchange platform who knows your identity, the transaction can eventually be traced back to you."

Surely we can see these BTC came from a mixer, and any compliant Cryptoasset Exchange Service Provider will know its came from a mixer and flag the transaction.

I will speak to my Chain Analysis TX monitoring guys, as this is very interesting. And Crypto from mixers should also be flagged, I am concerned of the transaction monitoring used does not pick up on this.
