Over the past few weeks we have been receiving large amounts of activity requests from kbin instances, primarily kbin.social. The issue is intermittent and the root cause is unknown. It appears as though some process occasionally gets stuck in a loop on the kbin side. For example, a legitimate user may upvote a post in one of our communities, causing kbin to send an upvote action, then an undo action, then an upvote action again, an undo action again, and on and on.
