Enforces HTTP signatures on object fetches, and rejects fetches from blocked instances. This should mean proper and full blocking of remote instances. This is now default behavior, which makes it a breaking change. To disable it (mostly for development purposes), the configuration item `allowUnsignedFetches` can be set to true. It is not the default for development environments as it is important to have as close as possible behavior to real environments for ActivityPub development.
