I just noticed my private instance, https://derp.foo/, was recently defederated by Beehaw. Thing is, I have no idea why. Was my instance accidentally included in some bulk defederation to get rid of spammers, or is there something specific to my instance?
Indeed it does. However, comparing it to https://derp.foo/c/hackernews and sorting by new reveals that posts more recent than 5 days ago were never sync'ed. In addition, https://beehaw.org/instances shows derp.foo as blocked.
