Dear MNHQ - I know this discussion has been had before but is it worth considering locking threads after a certain period of time, say a year or so, so that they don't suddenly appear in Active and prompt a bunch of new posters to reply to an OP that is several years old?
There's one on defibrillators that is 3.5 years old, that has just been reanimated by someone who works with defibrillators - I suspect a bot has trawled websites looking for "active" threads, which this one would appear to be as it's not locked out, and the poster has therefore posted on it.
What do you think about locking out zombie threads?
