If a databook makes a statement that contradicts the manga, what's wrong with citing it in the trivia section, rather than ignoring it altogether? Yes, authors make mistakes, big whoop. Kishi is not perfect. Make note of those mistakes then. We're Narutopedia. We should cite any and all information related to Naruto. We can't ignore information because we don't like it due to "contradictions" or "hypocrisy." If there's an obvious mistake, note it in the trivia section. We did that here. Seriously, I'm sick and tired of you all going at each other because of a databook and a manga over a fictional work on a fan-made site. Don't take this thread off-topic to bicker about them or about any little discrepancies you personally have, please.(I realize that this databook vs. manga thing will take this thread off-topic with the bickering it brings, so please stay on topic by talking about issues related to unnamed articles. Comments will be removed if they keep addressing the hot topic of "databook vs. manga.")
With that out of the way, I agree with TheUltimateThree and SnapperTwo, if it has merit, we should cite it, nameless or not. If it adds nothing, however, while it should be noted, it shouldn't be its own independent article. Some unnamed articles or proposals to add them typically add nothing new the wiki. (For instance, look here for an example.) But I also think some articles shouldn't be deleted because one user deems them not noteworthy enough. I do agree that some articles should not be created if they do not add anything new (which is where I see Seelentau's point), and should deleted if they do not add anything new and if the content of the deleted article is already noted elsewhere. But we can't ignore information by deleting it and never making note of it. And now I'm also confused as to why all of a sudden "technique" and "ability" are so different that articles have to be tagged for deletion. Have we discussed this before? (If so, link me please)
