I definitely believe that it's getting harder to get AAS thru customs. I recently had a package seized after getting a couple thru previously. Based on my experience & what a domestic source has told me, I believe that customs now x-rays packages coming into JFK. Not sure what criteria they use to perform this, but based on what I've heard & how I know that my int'l source had previously packaged my orders, I am convinced that x-ray is the only way they would have intercepted my order.
Hopefully, I'm just being paranoid but I don't think so
btw: it's my understanding that they flag addys not names because names can be the same; also, an international order that was seized & results in a flagged addy can also be a problem for domestic shipment as the USPS may also have the flagged addy
