This is difficult to hear but may be good feedback to share with kbin.social's admins and kbin's devs in the kbinMeta magazine. I don't want to see lemmy.ml defederated at this point, but it's a risky one to have on the front page. It's kind of nuanced:

Lemmy's devs have been running a successful campaign to recruit Redditors to use their app, and many Redditors have chosen lemmy.ml (the instance run by its developers) by default. A few of us have been trying to sound a warning about this, but it's muted amid the outrage at Reddit.

Lemmy's developers are often described as "tankies" but the word seems to be acting as a euphemism, as though it's just an eccentric subculture. The fact is Lemmy's devs are stooges for the CCP. They actively welcome its propaganda on their instance, and they've compiled apologetics for the CCP's human rights abuses including the Uyghur genocide.

At the same time, lemmy.ml is the primary instance for Lemmy, and an important support resource for instances that run on it. On top of that it's now home to a lot of Redditors trying to build their own communities there. For those reasons I don't think it should be defederated, but I think kbin.social might need a way to prevent the instance – or at least some specific communities – from reaching the front page.

For myself, I've blocked its china and technology communities, as well as a few specific users that I've seen post propaganda pieces there. I'm satisfied with that solution to address my own use, but your own experience makes me realize it still reflects on kbin.social to have that stuff reach our front page.
