Following up on an older suggestion in this very thread:
Back in 2023, @MusicListenzGood suggested adding a small bio + profile picture to ListenBrainz profiles, particularly to strengthen the social side of LB.
@aerozol replied at the time that a lot of that feedback had been added to the ListenBrainz Redesign/Figma discussions:
I got curious about what happened to the avatar part of that idea and did a little digging.
A month later, @mr_monkey mentioned having looked into adding user avatars to ListenBrainz:
Then in May 2023 the MetaBrainz team discussed profile pictures again, this time with the interesting idea that they might make more sense as something shared across MetaBrainz projects. Selecting artwork from the Cover Art Archive was also discussed:
So rather than suggesting the feature again: what happened to it? 
Was the avatar/profile-picture idea eventually dropped, blocked by some architectural/privacy issue, or did it simply never become a priority?
One thing that also made me curious is that MetaBrainz Community itself already has user avatars. Going even further back, when Gravatar was being reconsidered in 2018, there was already discussion about potentially using avatars from this forum instead:
I’m mainly curious about where the previous work/discussion ended before proposing yet another implementation of something that seems to have been explored several times already.
