I think it’s just their “Smart filter approved content”. This seems to remove just about all comment notifications and auto hides most comments on your posts so that they appear under “other” instead of under featured. You have to upvote them to move them to featured, so that by default most people don’t see comments on your answer.

It’s a good idea to deal with trolling and spam I suppose - but I can’t remember when I last got a troll comment on my answers on Quora. Not sure if I have ever.

I didn’t know what was happening for a while, just seemed to suddenly stop gettign any comment notifications and I assumed that for some reason nobody was commenting on my answers any more. Then I discovered this change. To put it back to the way it was go to:

https://www.quora.com/settings/n...

Then make sure Comments are switched on and select “Notify Me About: Everything”. And upvote any non spam / non trolling comments on your answers if you want everyone to see them easily.

To anyone who has commented on my answers - if you did it a few weeks ago - I probably didn’t get any notification of your comments. Please try again, just comment on your comment or message me.
