We have experts in our team who know what's not allowed in certain countries. There's a Google Adwords like system in place where once you post a package it is reviewed to check whether it's legal to take that thing to the destination city. The traveler is also intimated about any suspicious activity. I understand that this is just a preliminary check an that it's impossible to make the system completely bulletproof considering people find crazy ways to ship cocaine and drugs. But this is a chance we are willing to take. We try to do everything to ensure transparency and will plug all holes one at a time.
