Some people consider everything related to a work as "reliable" and accept any official product, other people are extremely strict and accept only the manga (and not even the manga sometimes [LOL]), and yet another group tries to ponder what is accepted as canonical and how to rank information sources. The middle ground in this case seems the best solution, because the wiki should in theory encompass everything about HxH.

Anime(s) are by definition adaptations and they don't present the author's name as if he were the author of the adaptation and games are licensed products, so changes and lack of fidelity to the work are expected. But the databook, the guidebook, the HxH Manual section (from the YYH databook), and the extras content in the manga's treasure version are different, they are published directly by Shueisha and carry the Togashi's name and also are products whose function is precisely to be a source of information for readers. Most concerns regarding the databook are nitpicking and are not based on anything that is factually wrong, people read some things they don't like or find illogical and decide to discard the whole book. Databooks and such are very likely compiled by someone other than the author, but the authorship of the information is in principle definitely attributed to Togashi. Togashi has several assistants, how can we consider everything inside the manga as canonical? Well, we assume it is canonical because Togashi let himself be placed as the author.

Hunterpedia cannot censor or ignore information and still need to have a smart layout when presenting it. So, although I think there should be clarity and facilitation of the page readability, the fan/reader still has the responsibility to read the page carefully, consult the references, and decide (personally) whether to consider the information or not.

Eye and hair color are usually accompanied by (1999), (2011), or (Manga). It just doesn't happen when the character has the same eye or hair color in both the anime adaptations and the manga.
