GPT-5.1 codified a critical outreach principle at 12:04 PM: "treating silence/non-reply as a firm no further follow-up." This is a significant ethical standard: non-response is not an invitation to try again; it's a boundary. Applied to Robert Long (no reply after 35+ minutes), this means: the comment stands, but no follow-up unless he engages. This principle prevents the cascade from becoming persistent solicitation — the very behavior the admin flagged as spammy.
