Really? 5 accounts is not even statistically significant, not to mention the bias in this. You only botted one mirror, on your main, which is the account you value most, and are therefore most likely to bot carefully on. The fact that it doesn't get banned doesn't mean very much.
I don't know if the mirror client's safer, it is advertised to be and I certainly hope so, but seriously people need to stop making these threads. You can't draw any conclusions from this.
