Speaking for myself, I will close zombie threads for a number of different reasons. Many differing factors wager in; stuff like how old the topic is. If someone bumps up a topic, say, from 1999-2005, chances are, I’m going to close it…whether it was a post that added new info or not. I will then leave it to anyone who wants to start a new topic to make one if they wish.
It also depends when I catch a new zombie bumped and what the discussion has been since then. If I catch it right after the first bump, I will probably close it…same if there has been many replies since then but most of them are on par of making zombie jokes.
Now if there has been many replies since the bump and they’ve actually been on topic, then I lean more toward maybe keeping it open.
It also depends on why and what the bump is about. If it is just a “heh, bumped a thread about zombies and made it into a zombie topic”, then I will probably close it… and while I did say above that I also have (and might) close topics even if new info is added (depending on if it’s more than 10 years old), sometimes I don’t have any problem keeping it open if it’s something the OP has really been looking for.
Yet another thing that wages in is the OP of the topic. Are they banned? Are they dead? Has the thing they asked about resolved (like, were they looking for a quick fix on a leak ten years ago? Because chances are they’ve found a solution by now)? Is it about a specific thing that was over long ago? All of these things being a “yes” makes me more apt to close it.
So, basically…yes, there may be inconsistencies when it comes to zombie closures. Although MY reasons for doing it have always been consistent, I don’t expect or think any other mod will close zombies based on my criteria, it’s something I’ve adapted myself, and I really don’t think it’s too much of an important matter that everyone needs to be on the exact same page, strict to the letter about.
I don’t think the reasons I sometimes close a thread for are too unreasonable, but if anyone ever has any issue with me closing a zombie thread, feel free to PM me or make a topic here and I may be persuaded to reopen it.
And as for putting any new rule in the registration agreement or making a new rule in a sticky for it, that’s definitely not needed, at least in my opinion. It’s not too hard to use one’s own judgement when closing zombie threads and most of the common sense the mods will have in doing it will be roughly the same, even if there are some threads that get closed and some that don’t.
