For those uninitiated - in the forums "necromancing" means "resurrecting" old (sometimes over a year) threads either with additional question or comment of questionable value (like "Me too!"). Some forums prohibit it, some not, but in general the practice is frowned upon in online communities.
With exception of adding a solution to a rare unresolved problem this seems to add no value and is usually source of confusion (the repliers might not look at the date) or just "digital garbage" (exhibit A - it's been said multiple times on SCN this is not feasible). Also only OP can close the discussion and assign points, so this seems unfair to the unsuspecting Samaritans in case the question does get any answers.
We've had some on and off discussions on this. Sometimes I report "necromancing" (with mixed success) but looking at ROE - there is no official community position on this. Is it time we add it?
