Possibility to "mute" users

What is the problem you are facing?

I see a person listening to the same artist everyday, I see almost only that artist all day looping in the "Recently listened" panel.

I'd like the possibility to not show the activity of that user, and extend it to the possibility to mute some specific users. There's also the possibility to make a panel that shows only the users wanted. So the solution would be a blacklist or a whitelist.

What are the possible drawbacks or issues with the requested changes?

I know it's really selfish, but maybe I'm not the only one so just in case I put it here. It's not urgent and I won't talk about it again as it's just a suggestion for something that bothers me :)
