Downloadable Files for Import

As of version 4.1, blocklist files can be imported and exported from the admin interface, under Moderation > Federation.
The command line tool fediblock-sync available from fediblockhole can be used to import blocklists from multiple sources, including remote servers, URLs, or local files.

How is the list created?

The Garden Fence blocklist is generated with a python script:

Reference Servers

The admins of these servers have given permission for their block lists to be used for the purpose of generating this combined blocklist:

The admins of these servers make their own determinations about which servers to block, and represent a variety of administrative styles and approaches to evaluating the importance of blocking any particular server. They do not necessarily endorse the entire content of the final blocklist, or suspensions made by other servers.

What this list is not

Neutral / Unbiased

This is not a neutral or unbiased survey of which servers are most blocked across the fediverse. It is highly biased against the various forms of unwanted content mentioned above.


This list contains only the most blocked servers among the selected group of reference servers. Some of these servers on their own have much longer blocklists, and there are surely other servers that you may wish to block that are not listed.

It also does not necessarily represent all of the different kinds of content that you might want to block depending on the goals and values of your particular server, such as porn, crypto, bots, etc.

It is also highly biased towards English content, and may not provide good coverage for content in other languages.


Updates are typically processed and reviewed once a week.
