A controversial developer circumvented one of Mastodon's primary tools for blocking bad actors, all so that his servers could connect to Threads.

Authorized Fetch (also referred to as Secure Mode in Mastodon) was recently circumvented by a stupidly easy solution: just sign your fetch requests with some other domain name.

    When it is turned on, an instance will require any other server to sign their request to fetch any post. This prevents “leaking” of posts via ActivityPub to blocked instances.

    Oh I see. Yeah that sounds pretty hopeless. Does it use the fetching site’s domain validated TLS certificate? Is the idea to permit fetching unless the fetching domain is on a blacklist? If yes, someone didn’t have their thinking cap on. The whole concept is dumb though, there is no way to prevent posts from leaking. The saying is that once 3 people know a secret, it is no longer secret.
