Then you claimed it without meeting the requirements of the technique AS STATED in the Anime. You were not, and have never been on those two accounts, a hunter nin of Kirigakure, and you were not, and will never be, taught by a hunter nin of Kirigakure. That wiki page was made that short time ago, if that is even the case, because of our lack of use of the wiki, and really, the very little weight we put into it because of the people who like to exploit it.
We tend to use Narutopedia for our information. I've posted the link to that page; I'm curious, since when are we going to start ignoring things to the Wiki that contains all of the information on the series?
I do wonder about the requirement for being a hunter-nin. The 'official' wiki states that it was used by A hunter-nin. Not that the jutsu is used exclusively BY hunter-nin. Although yes, many hunter-nin and ANBU types know all sorts of fancy jutsu does the anime ever say exactly where this jutsu comes from? Was he only taught it from kirigakure? Did he come up with it himself?
The nature of the vagueness of a jutsu like this to me gives it reason to be more of a claimable thing because there is no real ORIGIN of this jutsu other than "a kirigakure hunter-nin used it" Whereas things like the nara clan are much harder to claim because they have a solid place of origin (also it should be noted that it's not a village that controls nara so much as the nara clan itself).
Also I believe more people would be on your side Isa if you weren't trying to take away a jutsu that's been used for so long by so many without incident until now. There is a certain advantage to using the forums. If you guys noticed this problem occurring like you said on a small scale back whenever it would have been much easier to start a discussion and keep it under kirigakure's control legitimately.
To suddenly instill this rule when a majority of people didn't know it existed now would be...silly in my opinion. If Kirigakure has been following this rule it was never made clear to the rest of the community that it was meant to be kept secret. That is the main difference between things like Edo and Hiraishin and this.
