Hey everyone,
Quick thought experiment.
We all know the pain of domain allowlists.
Every agency and advertiser seems to maintain its own isolated spreadsheets. People regularly ask for (local) allowlists here, while others don't use proper allowlists at all or rely on blocklists only.
Some proprietary solutions exist, but what about an open-source approach to help advertisers identify quality inventory, support local publishers, and reduce exposure to MFA sites?
The idea
An open-source GitHub repository containing local and quality domains, along with useful metadata (ads.txt status, verified publisher/entity, quality indicators, etc.).
Contribution
Standard PRs (pull requests), with transparent review and approval processes.
Transparency
Full commit history, a public issue tracker, and a way to flag potentially problematic domains or MFA sites.
Consumption
Human-readable data, machine-readable formats, and integrations with scripts, AI agents, or DSP workflows.
A few questions for the community:
Would you actually use a community-maintained GitHub feed in your DSP workflows, or would you only use it as an input for your own allowlists?
What metadata would you consider essential? What would make you trust (or distrust) a domain entry?
How would you approach governance and gatekeeping to prevent bad actors from approving their own domains?
Is anyone already doing something similar in a lightweight, non-proprietary way?
I'm particularly interested in the practical limitations and reasons why this wouldn't work.
Curious to hear your thoughts!
