How it works
Each account reserves its matching nickname, ignoring case.
Unauthenticated users have 30 seconds to sign in; otherwise X assigns a guest name.
Protection resumes after X synchronizes. Service names stay reserved.
Legacy names over 30 characters remain reserved but cannot be used as nicknames.
Example commands
/msg X NICKINFO accountReviewed 27 September 2026. Current service settings and access checks apply. For the service’s current help, use /msg X HELP NICKINFO.
