Since I didntdidn't deal with this particular flag, these are my views as an AU user not as a moderator...
There are a few phrases that become red-flags in the eyes of users -
- hang
- freeze
- crash
- bug
AU is a member of the StackExchangeStack Exchange network. Its mission (paraphrasing) is to become the sum of useful knowledge for all well defined questions.
The red-flags I talked about are aberrations - out of the ordinary issues that affected one or small numbers of people & systems.
The question started off talking about a "hang" - thus this should start ringing alarm-bells. These aberrations are bugs - stuff that shouldn’t in reality ever exist and as such need to be fixed. Software development is rarely perfect. Thus problems do exist after release. On-going support resolves these.
AU is not a bug-tracker nor (rarely) a bug-fixing site.
Issues that affect individuals rarely contribute to the sum of useful knowledge that SE strives for. Those types of queries and issues should exist on bug-tracking sites such as Launchpad.
The close-voters most probably followed the same train of thought and pointed you in that direction.
As to the moderation aspect. You yourself added the "informational: bug report" comment. Looking at your profile, you are an experienced StackExchangeStack Exchange user and should recogniserecognize, comments do not - and should never - exist as an answer by itself. These comments should be part of a question (your question) or as a real comment under the question.
Since you own the question, you can re-edit your question to add that further piece of information.
and thanks
Thank-you for linking that other question. This falls into the same red-flag category and as such has been similarly closed.
