My guesses would be:
Because there haven't been that many worthy movies upped.
Because we seeming gain nothing by posting nzb's, only for talking nonsense in the actual forums, so it's less worth the effort.
I say this having shared at least a few NZBs before and still found myself only a "member" with 2 grabs, for lack of leaving useless posts.
lol, hope this was helpful.
