Lemmy.ml seems to block access to any requests with the specific user agent string “kbinBot” (and not just “Bot” or “Kbin”, so it seems very deliberate), which means the ~51.000 users on kbin.social don’t see anything new happening in Lemmy.ml communities.
It’s been brought up a couple times, but no lemmy.ml admin has commented on it yet.
It was less of a massacre and more a preemptive student debt forgiveness plan.
