An installation question was recently closed as off topic: https://askubuntu.com/questions/364945/server-13-10-install-hangs/364949.
I kind of understand the reasoning - it turns out the problem was a bug. The "auto reply" in the close message even stated it:
Bug reports and problems with the development version of Ubuntu should be reported on Launchpad so that developers can see, track and fix these issues...
First piece of brokenness:
How is one supposed to know bugs in advance? If I knew it was a bug, wouldn't the developers know it was a bug in advance? If developers knew it was a bug, wouldn't it have been fixed before being released?
Second piece of brokenness:
Why would Ubuntu moderators delete the comment with a link to the bug report (requested in the "close" comment")? What is the purpose of forcing users to hunt for a bug report? Assuming a user does not see a deleted comment, how does a user even know the bug report exists?
