Blocklist Index

NOTE: Mastodon.social and mastodon.online blocklists are provided for download as a sort of 'control group' for comparison, but are not weighted with other blocklists into the tiered blocklists.

• 100.percent.csv - Blocks that are on 100% of all blocklists for all sources.
• __allowlist.csv - The 'safelist' to ensure that accidental defederations don't happen. Nothing in this list will appear in a unified blocklist.
• _unified_tier0_blocklist.csv - Combines blocks from all T0 sources (Seirdy, Gardenfence, Council) into a unified Tier 0 file.
• _unified_tier1_blocklist.csv - Requires 50% consensus to appear on this list. Includes Tier 0.
• _unified_tier2_blocklist.csv - Requires 33% consensus to appear on this list. Includes Tier 0 and Tier 1.
• _unified_tier3_blocklist.csv - Requires 2 sources to agree for it to appear on this list. Includes Tier 0, 1, and 2.
• tier0.csv - The original Tier0 file. Algorithmic and curated. See Seirdy's Fediverse Blocklists for notes about the process behind creating it.
• gardenfence.csv - A mirror of the Gardenfence Tier 0 file.
• tier0-council.csv - Requires 80% agreement on blocks from trusted sources.
• birdsite.csv - All the Birdsite Live Blocks. This file is provided separately as a convenience.
• _unified_min_blocklist.csv - [Deprecated] Identical to the _unified_tier0_blocklist.csv.
• Other Files - Other files listed here are individual trusted sources who provided data for the blocklist.

Subfolders:

• mastodon - identical blocklist data, but with proper mastodon headers in format #domain,#severity... etc.
• other - These aren't blocklists, but reports.
