Age: a Didit provider behind the vendor-neutral age interface. A person verifies once (ID document, passive liveness, face match) and all their linked IMVU accounts count as adult. Webhooks are checked against Didit's signatures; only "over 18" is kept. A later answer replaces an earlier one (an approval taken back is revoked). Checks are limited: one unfinished check per person, 3 in 30 days, none once verified, and a monthly cap (DIDIT_MONTHLY_LIMIT, default 30: Didit's free plan is $10 of credit a month and a check costs $0.30). The Account page gets an Age Verification card. Registration: open or closed, an admin's setting in the console (default from REGISTRATION). Closed: new accounts can only sign in until a moderator approves them (or declines, deleting the account); the website shows them a waiting page and the API treats them as signed out.
