User:Yair rand/UserBlind.js

/*

Hide usernames when arriving through a certain kind of link. Replace all mentions of usernames with tokens like '[USER #6]'. Also hide any other identifying details like signature styling.

This is intended to prevent accidental bias. Users could still deliberately go to the page outside userblind mode. Could ask users to post whether they arrived via having some connection to the user? Better yet, build in commenting gadget which appends a UserBlind marker. This would depend on the honor system, people could post that themselves manually or even check outside userblind first.

This script is currently very unpolished and probably quite buggy. It's mostly a proof-of-concept.



// Test cases (TODO): // * "I mention User:Foo and some words. --User talk:Blah ..UTC" shouldn't strip the end of the comment. // * "I, User:Foo, say foo. --User:Foo (talk) ..UTC"

// TODO: User pages can't have edit or section-edit buttons. They would have to link to the page itself, exposing the user.

// New system: Priority markers. User: is top, followed by Talk/Contribs. High priority can plow through low priority as a sig, but not the reverse. There's still a potential issue of // pointing to one's own user page in a comment, though... Maybe cap by text size?

// TODO: When viewing #hash, update scroll position after loading.

// TODO: Remove '.title=[USER] - userName' mod before launch. // TODO: Remove console logs before launch.

// How to deal with userpage redlinks? Clicking on them points to an edit page, so we need a warning, but exposing them as redlinks in hrefs is identifying.

// TODO: Script shouldn't run if in edit mode.

// TODO: Eventually write some tests. Actually, lots of tests.

// IDEA: Work the comment gadget into this, so that users don't need to go to the edit page. // Even better: Users can type in '[USER #1]' and have this script replace it with the actual username.
