Wikipedia:There's a reason you don't know

Certain things on Wikipedia happen with little or no explanation. These include suppressions, checkuser blocks, many revision deletions, and many actions of the Arbitration Committee. Because most actions are logged publicly on Wikipedia, and their rationales well-documented, some users may get upset that they don't know why these things happen.

But things are only obscured for a small number of reasons. Sometimes it's because they concern private information that, for legal reasons, only certain users can access. Sometimes it's because excessive detail would help bad actors do more bad things or reward malfeasance with attention. And sometimes it's for the best interests of the editors affected, such as minors or those experiencing mental health issues. If you don't know why something happened, there's probably a reason. And it's probably a good reason. And by butting in without knowing full context, you could cause serious harm.

If you have concerns about the reasoning for something, there are procedures for questioning a decision without publicizing private information. Assume Good Faith applies to opaque actions too. If, say, an admin blocked someone without stating a reason, and this concerns you, usually the best course of action will be to email them and politely ask why. If you are unable to resolve your concerns this way, the Arbitration Committee is empowered to resolve any disputes involving private evidence. On a global level, the Ombuds commission also can hear complaints involving alleged misuse of checkuser and oversight privileges.

Don't be the jerk who prolongs someone's mental anguish, or gives attention to a long-term abuser, or helps a vandal evade their block, just because you were curious or because you leapt to the conclusion of admin abuse. Follow the proper channels to inquire about something or appeal a decision, and assume good faith of the user who made it.
