This blocklist is intended as a simple starting point for Mastodon server admins who want to protect their users from the worst and most well known sources of:
: The command line tool **fediblock-sync** available from [fediblockhole](https://github.com/eigenmagic/fediblockhole) can be used to import blocklists from multiple sources, including remote servers, URLs, or local files.
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.
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.
One of the aims of the Garden Fence blocklist is simplicity. There is only one list, it can be used for manual or automatic import, and I aim to keep it as straightforward as I can.
- [Seirdy's Fediverse Blocklists](https://seirdy.one/posts/2023/05/02/fediverse-blocklists/) has several manually curated block lists in different levels of severity.
- [Oliphant’s Blocklists](https://writer.oliphant.social/oliphant/blocklists) contains a variety of lists automatically combined from several reference sources.
