Should they? No, because they don’t pass the threshold of Insincere or Trolling. And Quora has enough ease already in hammering down contributions to Quora.
However, such questions are indeed fingernails on a chalkboard to anyone living outside the US. A renowned Quoran of the Hellenic persuasion has once described such questions to me as αμερικανιές /amerikanˈjes/.
The colloquial modern Greek suffix –ja, plural –jes, < Mediaeval Greek –éa, is a flexible and expressive morpheme. It is not, however, complimentary.
Downvote the questions. They won’t go away, and they seem if anything to have been templated, which would mean that Quora was complicit in putting them up: Question patterns by Jay Wacker on The Quora Blog; Question Patterns (Quora feature)
Oh, you didn’t know about templated questions? Well, now you do.
