I've used usenet for maybe 6 months lightly, so admittedly I'm not the mostly experienced. That being said, I know how to sort search results by popularity and size, and I've still had at least 5 video links download executables in that time, from various indexers. Maybe those .exes were completely innocent and not malware... But for some reason I have my doubts.

Personally I'd argue RD is actually cheap for video, and unless you NEED max download speeds, torrents are just as good as Usenet for anything else.

(Note torrents will probably need a VPN too, but that's still substantially cheaper than Usenet if you buy years at a time. And personally I use a VPN for usenet too, although I'm sure I'll be downvoted and called paranoid.)
