I raise this matter here because of comments arising against this question and others. I checked several earlier questions by the OP on that link, and in every case, the exact question had been asked previously on different sites.
My starting position is that I really don't like the idea of people trawling other Q&A sites for questions to pose here on ELU. Leading on from that, I'm not keen on people posting questions themselves somewhere else, then posting them here later. It seems to me this is "Duplicate Questions" by another name.
It's probably fair to say that a significant reason why I don't like this behaviour is that it's characteristic of one of our most troublesome trolls. My understanding is most Q&A sites at least take a dim view of multiple posting. Apparently not the current ELU mods, though.
Am I a lone voice here?
