Q&A absolutely should be banned.
Currently there are 491 pages of 50 questions each, meaning there have been ~24,550 questions answered by the Q&A committee. That's a lot of questions. That's suspicious to begin with because there surely aren't even 24,550 possible questions in the entire world, but even if there were shouldn't Q&A have already solved virtually every one of humanity's problems and ushered in a perfect utopia by now if something wasn't amiss?
It's obvious that Q&A is an ineffectual, likely even subversive element in modern discourse. There almost certainly exists some type of sinister purpose to the machinations of Q&A, and if we don't act and ban it soon that design will eventually come to fruition and we'll all pay the cost.
