@filippo One reason for that is content that's illegal to distribute in the location where the instance/instance's admin is. The instance _is_ redistributing content from instances it federates with (not only to its users, but also to anyone in the Internet via context of post pages). Also, there's some amount of media caching happening.

In case the issue is content that's not text, there are other options (disabling media caching). If the issue is distributing the content to ~anyone then silencing should help. If the issue is mere possession and/or facilitating transmission, then it's harder.

But that's not the main reason people do blocks~~~
