I have now set it to automatically close topics after 60 days, i.e. two months, on all category, except Staff, Wiki and Package Thread. Let’s see how this works.
Ah, thanks for the explanation! I haven’t noticed that any type of topic attracts spam in F-Droid, but we will see.
This goes into the right direction:
I just did it by closing all topics with the last activity happened before Feb 16. If I understand your message and the feature correctly, only newly created topics will be affected, so we will have to handle all topics that are yet available manually? Or will old topics, starting from tomorrow, be closed automatically, too?
