A pool is a set of publishers (hosts) and promoted models (targets) with the formats that go out and a schedule. Pick both sides from GET /cross-promo/accounts: every publisher needs an active session, every promoted model an active creative of at least one enabled format; a model without a creative of a format is simply skipped for that format (photos and texts are prepared in Studio). daily_limits is per publisher per day: story and mass_dm are sends a day, post is how many promo posts a publisher holds at once (each one rotates after post_ttl_days). Bio lines and friend pins run on their own refresh cycle. Mass messages need publish_settings.mass_dm.send_to: OnlyFans list names matched on every publisher’s page; a name a publisher does not have is skipped, and a list that is also excluded is never written to. Names are compared by letters and digits only (emoji, punctuation, spacing and case are ignored); exclude_lists also accept * for any characters, so *NO MASS* covers every spelling of that list. Rotation: equal promotes the least promoted model first, priority follows the order of targets, weighted shares mentions by target_weights (3 against 1 means three times as often). The pool starts active on start_date.
