I don't think adcoms will stay in their office until midnight just to call somebody in fareast whom they never know. Even the local US applicants, whose rec can be reached very convieniently, are partly background checked in few top schools routinely doing so. Therefore, for intl. applicants, if they decorated something about themself the chance being caught is far less. Take advantage of it if you have to.
but I do not think non-top10 schools will check so often. According to my experience, none of them contacted my recommenders later, though all of them provided scholarships to me.
