Intelligence != evidence. There is a high chance that this system resulted in multiple interceptions in the past, if a vendor ships out ten big packages at once and then one of them is intercepted, guess which packages are going to be scrutinized most heavily? The ten sent immediately before and after the one that was intercepted. I have noticed that bulk interceptions tend to happen in clusters, if one person has 1 kg of MDMA intercepted then all of the people sent MDMA in that shipping period have their orders intercepted as well. I have seen the same thing happen with bulk crystal LSD and other things. I would bet that it went something like this: A. Vendor sends 10 people bulk orders at the same time B. Dumbfuck customer checks his packages tracking with Tor which flags it C. Customs discovers it is loaded with bulk amounts of drugs D. Customs queries for all packages sent immediately before and after the intercepted package E. Customs intercepts 10 packages that are now flagged I am almost positive scenarios like this have unfolded before.
