When should a question be closed as a bug report?
Should we only close questions which would actually make valid report on the bug tracker? (and if so, how do we determine if a report would be valid?)
Should we close any questions which are definitely bugs, but may have been fixed or archived as TODO (not a valid report for the bug tracker)?
Or should we close questions which appear to be written as bug reports, but without enough detail to tell if it's a bug in blender or another issue?
We have had a wide variety of questions closed as bug reports, but may not actually be valid bugs that should be reported on the tracker. Such as:
There's also a few cases where questions which were about issues caused by a bug were closed even though the bug was fixed in a later version (and therefore would not be valid on the tracker), such as this one: https://blender.stackexchange.com/q/7075/599
And some cases where it's not obvious whether or not the behavior is a bug, for instance in this question: Black edges artifacts in renders on edges of geometry?
