Instructions

This tool is intended for Mastodon instance administrators

You can still play around with it even if you aren't a server admin, but + don't complain to me that you can't figure out how to work it :)

This tool is designed to suggest a blocklist that you may + want to configure on your Mastodon instance. The goal is to create a + system simpler than scrolling #FediBlock, more proactive than relying + entirely on user reports, and more federated than distributing blocklists + from a central authority.

To start, enter your instance's domain (no 'https://', no page, just the domain) + into the box above the synchronize button + on the right side menu, and click "Synchronize". This will make two calls + to your server's API to fetch the known peers and the block list. This + WILL require that your instance is configured to share this information. + This can be configured in your instance settings, under Site Settings, + enable 'publish list of discovered servers' and 'enable profile directory'. + Also set "show domain blocks" and "show rationale" as "to everyone".

Once you synchronie, any domains you have already blocked will appear + under Untrusted Hosts. All other known peers will appear under Known Hosts. + Now, you need to find some hosts you trust in the Known Hosts list and move + their slider to the right. The slider moves between -100 and 100, and once + you select a value it will update in the text box (you can also enter a + value into the box directly). This should + represent how much you "trust" this server, with -100 meaning you think this + server is "evil" and 100 meaning it is to be trusted entirely (at least for + the purposes of generating a blocklist). As you set values, these hosts will + move to Trusted Hosts or Untrusted Hosts accordingly. I do NOT recommend + trying to set a value for every single instance in the list. Search the page + for instances that you are already familiar with instead.

Once you have added a few trusted instances, click "Process" from the right + side menu. This will fetch the block list from each instance on your trusted + list. A host that appears on any of these blocklists will receive a negative + trust value equal to the trust value of the hosts that have blocked it, + multiplied by the appropriate multiplier values (configured in the side + menu), averaged by dividing it by the total number of hosts in the list.

Finally, you can use the "Export for Mastodon" button from the side menu + to export a blocklist as a CSV file, which you can then import into your + instance using the script provided below. This export will be + generated based on the Thresholds values set on the right side menu. Any + hosts with a trust value equal to or below the suspend threshold will be + suspended; any remaining hosts with a trust value equal to or below the + limit thershold will be limited.

Also please be aware that some instances may choose to obfuscate certain + URLs from their block list. Please don't do that. This tool cannot + work with obfuscated URLs.

The remaining options are mentioned below:

Hide Impotents: Tries to fetch a blocklist from all hosts in the list. + If no blocklist can be downloaded, the host will be hidden (They will NOT + be removed from the list, only hidden from display.) There is no point + adding one of these hosts to your trusted list if they do not provide a + their block list.
Find Enemies of Enemies: Creates a new list of hosts that are blocked + by the hosts on your untrusted list. The hosts on this list will NOT be + considered trusted or untrusted until you click the 'add' button to move + them into the main list with the given trust value.
Find Friends of Friends: Creates a new list of hosts that are in the + directory of the hosts in your trusted list. Trust values will be based + on both the trust value of the trusted host and the number of accounts + in its directory that are hosted at the this instance.
FInd Associates of Enemies: Creates a new list of hosts that are in the + directory of the hosts in your untrusted list. Trust values will be based + on both the trust value of the untrusted host and the number of accounts + in its directory that are hosted at the this instance.

+TODO:

Ultimately I do think this would make more sense as a shell script run + via cron job...but I think this is a better way to display the concept, + so that version is part two :)
