As part of trying to restore access to my disabled Instagram account, which I do now only for sport, without a sense of urgency, I received this very unusual error message from Facebook (even though, at the time, I wasn’t “on Facebook,” but rather “on Instagram”). I’ve written my fair share of error messages in my day, but I don’t think I’ve ever achieved this surreal height.
