Coincidentally, i bought myself a Synology NAS this weekend with the honest intention of using it mainly as a backup device, but while browsing the built in apps, i noticed a lot of the media download and streaming apps mentioned BT and NZB... took me a couple of seconds to realize what NZB referred to, but Im not really surprised that NZB has become an active protocol again, given how many consumer services make you jump through hoops to use BT.
I ran a local NNTP relay on my home phone back in the day. I recall spending quite a bit of time filtering out a lot of the binary groups.
