WMF don't hold lists of people's postal addresses, so they will need to contact people in order to send them T-shirts. By the time WMF contact Dr Blofeld, either Dr Blofeld might be editing again, or, if not, he could choose whether to decline the T-shirt at that time. There is no possibility of the T-shirt being somehow lost or wasted on the way to Blofeld's volcano.  (talk)
