A flagged name and its subdomains are served behind a warning that names the reason, the list and the report transaction. The visitor may continue, per name, for a day. The one refusal is the csam reason. /api/blocklist returns the subscribed lists and current flags, and /api/name/<name> carries the flag fields, for clients that cannot reach a full electrum server. It is a convenience copy: every entry names its report and can be re-derived from the list address. Flags are read once a minute from full servers and shared across requests; names are resolved without the extra round trip. BNS_BLOCKLISTS adds lists. The mobile constants now carry the default subscriptions for the consumer to come, and the docs explain flagged names.
