The Unread notifications and deleted edits discussion in Help talk:Notifications which hasn't received a comment for about 2 years recently rose to the top as it was unhidden as it was hid incorrectly. The topic is considered to be active 20 days ago as it was unhidden during that period.
Why is unhiding a topic considered an activity while it hasn't positively contributed anything to the discussion?
Opening or closing a discussion is considered as an action, because you sort of un/lock the conversation. The reasoning behind is that people should be aware of a reopening of a closed conversation (where a consensus has been found or a decision taken). I agree that that action should be filtered at some point.
I think closing/reopening of a topic is done using the 'Mark as resolved'/'Reopen topic' menu items. I'm speaking of hiding/unhiding of a discussion which is done using the 'Hide topic' menu and it's counterpart for unhiding a topic. How do they correlate?
Ha, I see. My bad on the misinterpretation.
I think that triggers a notification to informe people about that. while it is an activity, it triggers a notification and notifications could be filtered by user. That's all I can see. I can ask for more information. What would be your preference, to have an example?
As for my preference about whether hiding/revealing a topic should be considered an activity, I would not want it to be considered an activity. That's because it would then be moved to the top of 'Recently active topics' though nothing has changed from the perspective of a reader who is not watching in the topic. It might be worth notifying people watching a topic when it's getting hidden/unhidden but it's just not worth enough to reset an the last activity timestamp for the topic.
