Except that the newest Naruto movie was just pirated in the U.S. meaning that there should be an increased amount of traffic to the site. Not a decrease.
Once again, this is not a niche site like Heaven and Earth. This is a main Naruto site which currently is down to 5% of its total. I've provided evidence proving that at a time where there should be increased traffic because of the movies release it is not over even 500 despite the numerous fanclubs.
And the series isn't over by the way, part 3 was confirmed. Where is the buzz or members who are talking about the possibilities for part 3? Gone bc they did not like how the series ended.
All of the content for "The Last" has been available to the public for almost two months now. The ability to watch said content which you've been discussing over wouldn't be a large attraction. Besides that, most of these people probably watch the film on other websites like Youtube anyways.
No, it's down to 248 from some obscured daily average that no one has come forward to elaborate on yet. Whatever fanclubs that exist wouldn't increase the flow of activity just with the availability of the movie except to converse on subjects already talked about and to gush about watching the actual animation, artwork, or other technical facets of the movie.
Spin-offs typically don't garner the same acclaim like the original story does. You can continue applying blanket generalisations on why all of these faceless masses have supposedly left NF in droves, but unless you can get statements from all of them explaining why exactly they left the forum, this is only going to remain as some unsupported rumour.
