I am aware the nzbs are uploaded by users, but all the people checking tvnzb.com every day seem te be happy with it
however I don't know what info you have to say your 80-90% a real fact,
What I can say is that for the shows i'm watching, it has always worked.
It works because the editors change the titles and the show info (when they're about). I can confirm this because I watch the live feed and I used to be an editor (actually I think I still am
). It's otherwise almost completely reliant on 1 or 2 regular posters who know what they're doing. When they're away, TVNZB basically grinds to a halt.
TVBINZ was created out of frustration with this aspect of TVNZB, and also the other niggles, like: frequent dupes, only poster 'favourites' regularly available (hence very little x264), whole seasons not split into separate NZBs, nukes not removed from feed, no NFOs, no way of inspecting NZB contents, non-customizable feeds, IND posts, etc. etc. TVNZB still has its place, of course ...
