Thank you for those who offered me opinions and insights on this matter. Ray suggested that it is perfectly legal not to act unless my country imposes an obligation to act. In my understanding (which I admit is not very deep nor solid), there is such an obligation. There are some cases (defamation the most famous, but also others such as harm to a business) in which admins were found to be liable. An admin for Japanese wikipedia can be held liable, under japanese legal system, basically when 1) the content harms japanese (wikipedian, reader, or others such as a company), 2) I am aware of the content's illegality under japanese law, and 3) I do not delete the content despite that I have the ability (admin privilage) to do so. This part is just like in the U.S., I think. Potential issues here include invasion of privacy, defamation, obscenity, and copyright violation. But not very sure. Ray also suggested you can revert the deletion, and therefore there is no point of deleting or not deleting. But unless you are also an admin in Japanese wikipedia, I guess you cannot revert it. Mav suggested that after the act of submission is made, only illegality that matters is that of U.S./California law. I think otherwise, (i.e. legality of admins action/inaction also matters) but that aside, if mav is right, then some questions arises -- do Japanese admins should learn US/California laws in order to perform their legal obligations and protect themselves? Another question is if things like social reputation and privacy of a japanese citizen is protected under any U.S. law. If not, the implications include that Japanese admins should refuse to remove a content which violate privacy of a japanese citizen, written in Japanese, even when the victim asks to do so. As you can imagine, that this is against some peoples' ethical standards. regards, Tomos _________________________________________________________________ Add photos to your messages with MSN 8.
