After your first exchange you will receive a special Bitmixer code. This code makes sure that you will never receive any of the previous coins you have added to our reserves in any subsequent transactions you make with Bitmixer. In other words this ensures that you remain untraceable.
Day 1: I mixed U$100 worth of bitcoins and received a Bitmixer code so that when I mix subsequent coins I won't received what I previously mixed back. Fine!
48 Hours Later: I mixed another U$100 worth of bitcoins and received bitcoins back which none were of what I've mixed two days prior. Fine!
36 Hours Later: I mixed another U$100 worth of bitcoins and received bitcoins back which none were of what I've mixed two transactions prior. Fine!
Question: How were the last two transactions achieved given the following? ...

Clearly, my Bitmixer code remains on file attached to bitcoin wallet addresses I've previously used, else there would be a strong possibility of me receiving some of the coins back that I may not want attached to me, but that would be an impossibility given that ALL order data is purged from your system within 24 hours, as stated above, resulting in the 3-LAs et al. finding nothing.
Further, I'll be paying you a fee to mix coins stemming from a nefarious act with the strong possibility that I'll be receiving coins stemming from a nefarious act tens of times worst than what I'm tryin' to hide. Surely, wouldn't that bring the feds to my door a knockin' a helluva lot quicker? It'll be pretty embarrassing for me to defend myself if accused of running a underage goat brothel when in fact I ONLY pimp out adult chickens and occasionally a matured goose (soon to pimp ducks - drakes and hens).
Humor aside, I look forward to your reply, devs.

That was a fine observation on my part, eh? Sadly, nobody else caught it but me. To date, this is how the issue has been addressed - CRICKETS!
