    $\begingroup$ I downvoted this because I don't like how it's already part of another question. You're splitting one question/riddle into multiple questions. $\endgroup$

  • $\begingroup$ Yeah. I don't like that either. I guess we have a problem in that this behavior hasn't been defined as OK or not in this board. It's an odd/new situation that doesn't really apply anywhere else on SE. I'm going to take back my downvote and try to bring it up on the meta sometime soon. $\endgroup$
