Ayrt I mean even if your person does Google themself, nothing is stopping the writer from posting a link on unlocked social media after reveals (like many people do) or third parties who don't know anything about the fandom community from reccing it where it'll be found. (and look, most of the sort of people who go looking for fic of their stuff have AO3 accounts at this point anyway.)

Within some fandom communities "don't even talk about it outside lock" is standard but if you nommed it for yuletide you're the one who broke that.
