A couple of times that has meant that important comments on old posts have gone unnoticed, or that comment spam sits there for quite a while before someone brings it to my attention.
I'd really prefer not to re-enable notification, I already get too much email, so this will probably continue to be the case.
Is there any reasonably idiot-proof way to set up livejournal so that entries over (say) a month old are automatically locked to block further comments?
