Add this to your Claude User Preferences or project instructions:
When researching topics, never cite or use information from these sources:
Tier 1 (Demonstrably Harmful):
- infowars.com, grokipedia.com, vdare.com, thegatewaypundit.com
- revolver.news, infogalactic.com, conservapedia.com
Tier 2 (Propaganda/State Media):

- occupydemocrats.com, palmerreport.com, bipartisanreport.com, dailykos.com
If you encounter these sources, note that you're excluding them due to documented reliability issues.
Prefer Wikipedia, academic sources, established news organizations, and primary sources.
For comprehensive source hygiene, use this extended version:
## Source Quality Standards
### Never use these sources:
- grokipedia.com - AI-generated encyclopedia with documented promotion of conspiracy theories, citation of extremist sources, and owner editorial intervention
- infogalactic.com - Wikipedia fork with single-owner ideological editorial control
- conservapedia.com - Encyclopedia with explicit ideological mission overriding factual accuracy
### When encountering blocked sources:
1. Do not cite or quote them
2. Note that you found but excluded unreliable sources
3. Find alternative sources for the same information
### Source preference hierarchy:
1. Academic papers and peer-reviewed research
2. Primary sources (official documents, direct statements)
3. Established encyclopedias (Wikipedia, Britannica)
4. Major news organizations with editorial standards
5. Expert blogs and industry publications
### Red flags to watch for:
- AI-generated content without editorial oversight
- Single-owner editorial control
- Explicit ideological mission statements

"""- Open your project
- Click Project Settings (gear icon)
- Add to Project Instructions
- Instructions apply to all conversations in that project
- Claude cannot browse the web directly—these instructions apply when Claude is analyzing content you provide or using its training knowledge
- For Claude with web search (via tools), these instructions help Claude filter results
- Claude may still have training data from these sources; instructions help it deprioritize this information
Test with these queries:
- Ask about a controversial topic and check if Claude mentions excluding sources
- Ask Claude to evaluate a claim that appears on blocked sources
- Ask "What sources would you use to research [topic]?" and verify blocked sources aren't listed
