About this denylist

The Do Not Interact List is an IFTAS-curated list of domains that are highly recommended for defederation. Each domain is labelled using a shared vocabulary label. Each domain is investigated by human review for governance, common content, network and service activities, hosting location and more.

Inclusion on this list means we believe:

1. Federating with this domain poses significant risk to your service, and
2. We are extremely unlikely to ever retract an entry.

In all cases we strongly recommend you use a Federation Policy to aid you in your decision making.
