What means the icon key by some threads

I thought after one month after last replay the tread is closed with icon key
I see here old threads without key.


I am not sure, but I think that very old threads will not automatically close after 30 days, and if someone posts to one of those threads, they will continue to stay open unless a human being at Omni closes them manually.

For example, this thread was first posted in 2014, and it is still open despite the most recent post being in October 2022.

I think this usually happens when someone searches the forums for a topic, discovers an old thread, and then contributes to it without noticing how old it is.

This topic was automatically closed 30 days after the last reply. New replies are no longer allowed.
