Anyway we can increase auspice by learning from each others mistakes. For example how do they catch PO Box users? Has anyone been to court after accepting or rejecting a controlled delivery and beat the case? Whats the percentage of CDs that are personal use? Do big cities throw away personal use cases, and smaller towns keep them maybe? Do they ever let us keep packages and charge us later? Let's all work to never get arrested!

That list complied by u/gwern has all known or semi-documented arrests related to DNM activty. Only a small few have escaped a controlled deliveries. I do believe the ones that did escape conviction did sign for their package and feined knowledge of its contents while having a clean house.
