Anyone who got the link should be able to delete the file.
This should deter one from using the file sharing tool as free hosting for possibly bad content. One can also build a bot that deletes every file found on public internet.
Anonymous file hosting isn't something I'd be keen to offer, given the nhmber of people who would happily just abuse it.
Imagine some computer work with a class of high school kids, where a teacher has to send them a file... there will be maybe three full downloads max, before someone presses the "delete" button.
Sure, it wouldn't work for a large public setting... but it'd work for many other settings.
