What is The Bad Space?

The Bad Space arose from a need to identify instances that house bad actors, are poorly moderated, and/or contain inappropriate/offensive content (CSAM, hate speech, fascist ideology, etc.) that puts marginalized communities at risk.

It is an extension of the #fediblock hashtag - orginally created by Artist Marcia X with additional support from Ginger to provide a catalog of instances that seek to cause harm and reduce the quality of experience in the fediverse.

The searchable online catalog is built and maintained by Ro. The repo can be found here.

How does it work?

The Bad Space is a collaboration of communities, referred to as Current Sources, committed to actively moderating against racism, sexism, heterosexism, transphobia, ableism, casteism, or religion.

These communities have permitted The Bad Space to ingest their respective blocklists detailing their silences and suspension to create a composite directory of sites that engage in the behavior(s) listed in the section above. For each behavior, the directory of locations can be searched and, through The Bad Space's public API, integrated into external services.

Adding Locations

Current Sources continually review the #fediblock hashtag and update their silences and suspensions when warranted. If an instance meets the criteria of a Current Source to be suspended or silenced, The Bad Space will automatically be updated according to said Current Sources' curated data. For an instance to be listed on The Bad Space, at least two (2) Current Sources must have that location silenced and/or suspended. Instances will not display in the directory until two (2) Current Sources have taken moderation action against them.

Removing Locations

Locations that are displayed in The Bad Space may petition to be removed from the catalog by sending an appeal request to The Bad Space. The appeal process is outlined here.

How do I use it?

The Bad Space is meant to be a resource for anyone looking to improve the quality of their online experience by creating a tool that catalogs sources for harassment and abuse. There are several options for how it can be used.


To see if a site is listed in the database, use the search feature to search for that URL. If it is in the database, information for that instance will be returned and associated instances if applicable.
