i wouldnt want to guess on stats of incompetant configuring vs intentional blocking of uploading or try to guess/assume which is the case in a general statement. There are however isps/businesses/schools that allow incoming dccs but object to sending them. In some cases i imagine its a security issue, in others a means of limiting bandwidth useage by those who want to run fservs. Wouldnt surprise me if there isnt an element of hrm, best not block downloading right now or we'll lose business, so lets block sending to cut down on bandwidth useage and see if that flies. If an entity wants to restrict the use of sending, seems to me that would include any and all means.
