Sorry to go off topic here, but it seems that no messages are coming in and out from kbin.social.
See, e.g., https://kbin.dk/m/kbinMeta@kbin.social/t/3054/Lemmy-ml-is-blocking-all-requests-from-kbin-Instances and https://kbin.melroy.org/m/kbinMeta@kbin.social/t/2560/Lemmy-ml-is-blocking-all-requests-from-kbin-Instances
In the spirit of a thriving fediverse, I suggest not to assume the worst of other parts of it before we know a bit more of what's going on.
