I've been going through and flagging old posts that are now considered non-constructive or off-topic, using queries from Can Community help a brother out? Since I have more then 10k reputation, my only flag options are "Other" and "Very Low Quality".
If I select "Other" then the flag can only be seen by moderators, which means more work for them. If I select "Very Low Quality" then any 10k users can see it and we can close it without moderator intervention.
So "Very Low Quality" works better, but the questions usually aren't very low quality. Which should I use?
