Honestly, I've been using an alternate account on Mastodon, and until recently, I wasn't aware that this was such a significant issue on other Lemmy instances until you started to clearly communicate it to me. I've temporarily taken a few additional steps to reduce the spam intensity. By the end of September, kbin.social will receive an update that should address the federation issues.
