A well designed mixer would not be so easy to detect. In a perfect world, you'd have matching clients all the time, and the only contamination is the fee being siphoned off. If the fee is managed well it could be very difficult to determine coins that went or came from the mixer.

In reality, you probably need to batch a few customers together: 10 customers putting in 1 BTC, 1 customer putting in 10. But these don't need to be long-lived groups, if the mixer has the volume. So "their address" would only be the same for a few customers. An attacker would need to constantly make transactions to determine the addresses involved.

Most mixers give you completely "clean coins": That is there's no transaction chain from your inputs to your outputs. So they are probably doing some sort of system similar to what I describe.

The proper term for this kind of activity is money laundering.
