You get no argument from me on this point. HOWEVER, if Mr. Fly Stuff Businessman outsourced someone to set all this up, which is most likely the case, then he may not know there are any restrictions in place.
Someone needs to contact this guy and let him know business is being lost so he can figure out why and fix it.
If he is simply ignoring international biz, he is a fool. It is too easy to protect yourself these days. Take PayPal and you are covered, even with international sales, as long as you follow the guidelines.
