I think personally this is a bad move.
I think a substantial part of the user base is here for the free, easy access to torrents ---> no free, easy, access to torrents, no more of those users.
It would be better if we could at least host the torrents on another site; and I think the all the notifications about other sites hosting malware masquerading as fuwanovel translations is a pretty good indication of what could happen if all the torrents shut down. They'll still be distributed, but in a much less safe, and more dangerous way.
The users of the forums and twitter and facebook will still stick around, because they're already hooked on vns. It's preaching to the choir. (Not that that's a bad thing; I'm in the choir too).
To hook new users in, there needs to be easy access to free, good, vns. Some people are lazy and some people are horrendously bad with computers; and some people don't want to take the risk of malware that torrenting on a website of questionable reputation brings. The stream of new users, as in new to vns, will probably stagnate. The site will survive, but more as a stronghold of vn users rather than a site for conversion.
As to the fact that fewer users of the twitter and facebook use torrents than expected, its probably because the sample is skewed. Users of the facebook and twitter are probably more dedicated and downloaded what they wanted already; the new users, the more important ones, are the ones not surveyed and probably downloading the most.
I feel fuwanovel originated as a reputable listings site, and that's the core of its services. Without accessibility, it sort of loses its power, or changes the site fundamentally, from a vn sharing site to a vn promoting site. Which are two very different things -- not necessarily bad things, but two very different ones with slightly overlapping demographics.
I hope this site the best, but I'm probably not going to follow it very closely from now on.
Thanks for the awesome experience!
