Pretend you received an anonymous letter or small package in the post. How much could you tell about its origins from the envelope - ie, do letters and small packages sent through the US mail get franked with a time and place of posting?
What about if you got an anonymous package from one of those delivery companies like UPS? You sign for the package, and then what? I guess you could probably trace it back with UPS, but maybe not all the way back to the sender?
Or, look at it another way - if you wanted to send an anonymous package and make sure it wasn't traceable back to you (including when and where you sent it from), what would you do?
Thanks!
