I migrated that question in response to an explicit flag on it from a serious contributor to the Linguistics SE site specifically asking for the question to be migrated over to Linguistics.
Being myself no more than at best an infrequent contributor to the Linguistics site, and seeing as how the flagger was more than that, I took that flagger up on their request without further investigation. They’re someone who knows what they’re talking about in matters of general linguistics.
The way you “stop” such things is easy: you politely ask that the ELU mod team please coördinate more closely with mod teams of other sites as needed before migrating questions to sites they are not themselves themselves frequent contributors to.
In practice, this means talking to Alenanno, who was sleeping at the time. :)
