META: Could we maybe instead of locking the whole topic just remove some of the offending posts (give posters a timeout if you're inclined to) and let the original topic continue? It seems unfortunate to let a mostly interesting post get nuked due to a few posts.
Well quite. Temporarily closed for housekeeping.
Edit: done. Let's not bring up that stuff again, please. And no sniping; next person who does that gets uninvited.
