New: actual registration time. Random: a stable random ordering for this browsing session. Active: original public personal posts published in the preceding 30 days, excluding shares, private, restricted/gated, group and page posts; activity requires opt-in. City: only an explicitly entered, display-consented directory city. Shared interests: only mutual matching opt-in and authorized visible selections. UTC age cutoff uses the self-entered date of birth; it is not identity verification. Visibility and blocks are checked on every page; changing privacy can change the list.
