I think this rule needs clarification... i support the mods in everything they do, but we need to have like a limit, like you can't post in topics over 1 year old or something.
Cause i regularly search for topics just to make sure they haven't been created and post in old ones.
I know you could argue, that if they are that old, they aren't worth reviving.
Also, maybe Jim could program an auto lock or something on the old topics, would be as simple as:
UPDATE topics SET lock='1' WHERE DATE_SUB(CURDATE(), INTERVAL 1 YEAR) <= date
