The original report: ``` Good morning, I am reaching out about the issue with what seems to be a stale result sticking around when using seccdn for my account for this email address. https://cdn.libravatar.org/gravatarproxy/1cec8c7fd6cbcdb62ec2a89a105b591f?s=128&default=mm ^ this one shows no image (just the default image) https://seccdn.libravatar.org/avatar/1cec8c7fd6cbcdb62ec2a89a105b591f?size=128&default=mm ^ this one shows an image from +6 hours ago which has been deleted ``` Interestingly, a forced refresh led to the cache being refreshed and the problem gone. Anyway, the topic here is: If a user deletes their profile from libravatar, we should also trigger a cache refresh - background job would do fine here.
