User blog comment:Essie Essex/Necromancy discussion/@comment-27038417-20151023185033

I do like the idea of turning it into an actual warning with information on what they did wrong, so that it doesn't seem like we're bullying new users by posting it every time someone accidentally replies to an old conversation thread.

I'd say a reasonable amount of time to consider a comment necromancy is if the last comment was over, say, six months ago?

Types of comments that ought to warrant a reminder/warning:

- Responding to a question that someone asks that is either answered in the article or has already been answered by another commenter a long time ago.

- Useless/one-word answers (e.g. answering simply "Yes" if someone asked "Is Black Sally still alive?" a year ago).

- Making jokes or witty comebacks to a thread long past its expiration date.

- (obviously) troll comments which the author should be getting a warning for anyways.

Also, while necromancy is a very minor offense, it has a few negative repercussions like clogging up the recent activity section with irrelevant comments or sending emails out to people who may have been following the thread. Maybe in our warning/reminder we could also encourage users to start their own discussions in the comments rather than try to add on to ones that are over a year old?

Let me know if you agree/disagree.
