Not the ones from 2007 that we were being treated to a while ago, that was someone stirring. But the ones that are popping up now from much earlier this year.
There's a new feature on the boards. Below the posts on a thread and before the box where you can post a reply, there is now a list of 'similar threads'. I've just clicked on a couple at random because I was curious, and got a thread from April this year and one from August. So when threads from a few months ago pop back up (as I've seen a couple on the S&B board) it's not the poster's fault. They haven't deliberately gone looking for old threads to resurrect, they've been led there by MNHQ. So much for asking MN to do something about zombie threads, they're actively facilitating their revival.
I shall now toddle off to site stuff to recommend that the feature is removed as fast as it appeared.
