File-sharing in such form may not be anonymous, for example one may keep a snapshot of what's on that disk, and then check again after somebody have used it. That could catch anyone wet-handed for sharing anything, albeit legal or illegal. The anonymity is not as easy to preserve as it sounds like.

Likewise some may put virus into the disk (internally or automatically due to the virus itself) which the next person may not have their computers patched and have no anti-virus installed.

As a security guy, the idea of connecting this to my system scares the bejesus out of me. I want to point two small things out: USB device drivers are universally poorly tested, and this device could be anything. There's nothing stopping such a device from running an exploit in ring0 and taking full, instant control over your system.

As with any time when you couple your device with some random hole you should take all necessary precautions to avoid contracting a disease.

(I know this comment was intended to be largely funny, but I feel I need to point this out.) Thing is, this isn't like downloading some files, but like dropping a random PCI card into your box. By connecting this to your system, you're really ceding complete control, with effectively no way of preventing any attack from taking place. Is it likely? Not particularly, but it's definitely possible.

It's intended to be serious, I just decided to add the humorous slant to it after I started writing.

If I were to use data from these drops I'd want a junk system that I could flatten between uses dedicated to the task. Connecting random usb devices to your system is a recipe for disaster in a billion ways. Even connecting well behaved usb devices to your system with unknown data on them is fairly risky due to the poorly chosen default settings of popular operating systems like Windows.
