tordemon is correct, if you check your package's DCN at a net cafe or coffee shop's wi-fi then their router will almost certainly keep your MAC addresss, and MAC addresses are traceable to your credit card, which is traceable to your address etc. Unless you've paid for the laptop with cash or a prepaid, and only use it for this purpose, then...You should use the internet cafe's computer to check a DCN and wear sunglasses/hat for the CCTV's benefit. It is summer, this is normal, not suspicious.If you were using a proxy or the Tor network, this wouldn't matter. But you can't, and so it does.dankology, this is not a crypto-cyber-international-drug-smuggling-punk urban legend, we have been told this by people who *work* in the postal services industry. I heard this long before I arrived at SR.Remember the anthrax letter scares in the United States a while back, it was probably implemented for a reason like that. Anyway, you're annoyed at the moment so you're unlikely to agree with me. Still, it is true.P.S. This does not have to a theoretical debate. Send ten packages of low possession quantity e.g. 1g of weed to a person who is not connected to SR or a drug user but agreeable to have packages arrive for a fee and knows to follow procedure i.e. the name on the package isn't for that person and the person writes 'return to sender' and drops the packages back to the Post Office if they arrive. Repeatably check the packages on Tor everyday. -> Count the love letters. Statistically a max of 1 package ought to be intercepted for the average vendor, given that 97% of packages reach their destination without difficulties. If it's larger than that, then another variable is in the picture.
