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.

    Authorised Fetch existed long before Instagram Threads. 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.

    This setting is turned off by default, because some software are incompatible with it (like /kbin, Pixelfed before June 2023, maybe Lemmy too), because it makes server load higher, and it may make some replies missing (at least on microblogging side).
