So this post is posted on 22/09/20 and you can still reply comment: https://www.ozbargain.com.au/node/567679
But this post is posted 25/09/20 and it is locked: https://www.ozbargain.com.au/node/568392
I thought it is maybe due to second post is "expired" but I checked other expired posts and you can still reply comment.
Please explain ozbargain how come the post with earlier post date is still open to reply, and post with later post date is locked. Confusing.
