Urban Dead was what came to mind for me too! That was going to be my rebuttal to the comments saying "The only reason to limit stuff is paywall." Kids these days can't imagine life in the Internet's "make some shit just because it's cool — if it gets too popular we'll sell t-shirts" era.
That's more interesting an answer than I was expecting! I didn't even consider that any floppy disk Mavicas could be modern enough to have USB. The only time I used one of these, you could still assume a floppy drive in every computer.
Even an RSS extension? This means war.
