This is starting to sound the game of Telephone or Chinese Whispers.No, of course they can't get your IP address if you're making a data request via the Tor network.The issue is that it's likely (and easy) for this sequence to occur.Accessed by Tor exit node (the list of these IP addresses is publicly available). Throw up a red flag. It is interesting that somebody who wants to be anonymous is checking their package delivery data. Record data request and monitor future deliveries to that address for suspicious packages.I never understood why people thought this was a spectacularly strange endeavor. Homeland Security, Anthrax anyone? Seems more like common sense from the perspective of the postal inspectors surely, they can't look at all the packages but they sure can look at all the packages that are looked at from Tor exit nodes.The other thing is that checking your package delivery data from a 3rd party provider may not be the help you imagine, it's simple for the 3rd party to relay the IP address being used to access their service as part of the tracking package request. This is a bit less likely maybe, but there is no great technical difficulty in them doing so. I advise people not to use tracking, and that if they really need to use it, that they use it exclusively as a way for the vendor to prove that package A went from Y to Z if the package goes missing. You shouldn't on one hand claim you never expected a package containing drugs and then on the other hand check it umpteen times on Tor. Sure nothing can be proven, but it looks hella suspicious.Other people have other opinions, it's been discussed before exhaustively, but those are mine.
