Relevant issue for gracefully handling 403 errors is here

Yes, folks have tried reaching out in their Matrix chat without luck so far.

There's https://fedidb.org/software/kbin, but this hardly helps users differentiate based on various instance characteristics like joinmastodon.org, for example (I have no experience with Lemmy's instance listing).

Relevant question on Lemmy.ml, in addition to prompting on Matrix is here: https://lemmy.ml/post/1563840

Unfortunately, as of right now, no. This may change in the future, but currently it's best to decide on a Kbin instance early on so you don't have too many posts and comments that will be left behind.

There's also the possibility of having multiple accounts, but that's cumbersome for a multitude of reasons.

Is this on the homepage, on the linked post, or everywhere? Definitely not expected behavior.

Regarding missing user avatars - there is an open pull request to replace these with a remote instance's logo, rather than the browser default for unlocated images: https://codeberg.org/Kbin/kbin-core/pulls/334

Additionally, I've tweaked some things server-side and it looks like that's helped caching remote avatars (but there's still work to be done). Please keep me updated on any further issues.

Thanks, I had to step away and was pleasantly surprised by this being debugged for me by the time I got back! 😊 I've pinged the Kbin space on Matrix to see if anyone has thoughts on how we can re-download these avatars. I may end up writing a custom script to handle this manually if there's no way to trigger a warmup on media cache.

Currently debugging this. I'm just using the default styles found in /kbin so I'll need to experiment a little. I'll follow up here.
