One Piece Wiki:Guidebook/Spoiler Rules

What is a Spoiler?
A spoiler is information released that gives away major plot points or current storyline information.

Are they accepted by fans?
In general yes. However there are many fans who hate to be spoilt and don't want to know the outcome of current manga events in One Piece. Many are still reading early chapters of the manga or watching early episode of the anime. Often knowing what the current storyline holds puts off fans from watching the past storylines, or the anime altogether. Spoilers can anger many fans as they feel they have been robbed of some enjoyment in watching the past episodes.

Are there false Spoilers
Yes indeed there are.

While the majority of One Piece fans in the English Speaking community do not know how to speak Japanese, there are several that do. It has not been known for them to release fake Japanese text and/or translations into the fandom to confuse or misled others. Many English speaking fans therefore take this as true spoilers without knowing they are being duped.

Sometimes the spoilers take form of fanfiction materials or an attempt to make predications that seem true but prove to otherwise be false. It is important to remember this when adding spoilers upon their first day release.

Often fake spoilers come in one of these forms:
 * Common fanfiction materials
 * speculations
 * predications
 * False or misleading Translations

Example of a fake Spoiler:
This is an example of a fake spoiler posted with Chapter 433 of the manga:

扉絵「うさぎ人間とエネル」

木材アダムの前に海軍以外集合、そして船の着工に取り掛かる 回想ガープ、用件はレヴエリーが開かれるのでその前にルフィを七武に勧誘 ルフィ断り、ガープ去り際に次会う時は捕縛するが今日は祖父としてきたと帰る コビーも同じく警告するがルフィ笑顔で「しょうがない」と答える 画面切替アラバスタ、コブラが通路を歩きながらイガラムとビビと会話（レヴエリーの為に出航） 白ヒゲとシャンクス対面、エニエスロビーの話題からルフィの話題になりエースの話題へ 白ヒゲ、エースは裏切り者の黒ヒゲを追っていると言う 海の上でエース居眠り中、目を覚ますと遠い所に黒ヒゲの旗の船発見 エース「見つけたぜ！」

In this spoiler Igaram, Cobra and Vivi were seen to be talking about Shanks and Whitebeard meeting each other. It also stated that Ace had found Blackbeard. It stated that Garp offers Luffy the Shichibukai position but Luffy refuse, it spoke of Garp warning him he'll arrest him next time. It stated that Whitebeard told Shanks Ace had not found Blackbeard.

This was later proven false. It was actully a rabid fanfiction material written by Otakus or Attention-grabbers.

However there were several things in this text that were true and made several translators believe this was a true spoiler.

Rules

 * Do not post fake information from fake spoilers.
 * When the spoiler is released, do not add the spoilers until the confirmed translations are released, normally a day later.
 * Remember pictures as well as text are both counted as spoilers.
 * All pages containing spoilers must be marked up with a spoiler warning.
 * If you read a 'spoiler' marked page and are 'spoilt' as a result, do not complain about it as you were given warnings that you yourself choose to ignore.
