New settings, in Settings/Preferences screen, off by default:

Filtering room directory

Also migrate RoomDirectoryService to coroutines (#2449)

May I have two questions here?

• I think "Filter NSFW rooms" might be easier to find.
• How exactly does the filtering work? The Blender room, for example, has "No NSFW Media" in its name description. Would it be hidden then?

* I _think_ _Filter NSFW rooms_ might be easier to find.

"NSFW" is not understandable enough for non power users.

* How exactly does the filtering work? The Blender room, for example, has _No NSFW Media_ in its name. Would it be hidden then?

Yes, I have seen the problem with the Blender room, it will be actually filtered out. Filtering like that is far from ideal. This is a first quick implementation, we will do better in the future (filtering server side, new state event describing the room content, etc.)

Thanks for the quick response!

"NSFW" is not understandable enough for non power users.

Maybe "Filter explicit content" or something like that. I would just expect the explicit word to be in the "header".

But I am probably just nitpicking at this point... 😂 Sorry for annoying

I have created https://github.com/matrix-org/matrix-doc/issues/3054 to try to do better on this subject

Update wording

FTR I have asked the admin of the room about Blender to update the topic of the room to avoid being filtered by mistake.

I couldn't suggest a better way for now, will think later.

LGTM, cool!
