About this denylistThe Abandoned and Unmanaged list is an IFTAS-curated list of domains that are highly recommended for defederation or limited delivery. Each domain is labelled using a [shared vocabulary label](https://about.iftas.org/library/shared-vocabulary-labels/ ). Each domain is investigated by human review for governance, common content, network and service activities, hosting location and more.
Before including any domain on this list we perform the following efforts to ascertain the service status:Spam accounts are reported to the domain and monitored for mitigation. After seven days, if no mitigation is observed, the listed admin is contacted on network. After seven more days, if no response and no mitigation, the listed admin is contacted via email if publicly available. Where appropriate, DNS/domain registrant contact information is used if available. After seven more days, if no response and no mitigation, the domain enters the AUD review process.
Domains that do not publish contact information may enter the AUD process sooner than the minimum 22 days. Domains that have active human presence may be recommended for a Limit/Silence, domains that are predominantly serving bot content may be recommended for a Suspend.
The AUD list is available as a default option in the following platforms:https://blog.anew.social/launch-domain-blocklists/">BridgyFed https://discover.holos.social/">Holos Discover https://newsmastfoundation.org/">Newsmast https://activitypub.space/topic/be4aa1b0-c10e-429d-a948-5c51133bf4a6/https-archipelago.1sland.social-fires/8">NodeBB https://activitypub.blog/2025/12/17/7-8-0-happy-holidays/">WordPress
Inclusion on this list means we have observed this domain:is a dedicated spam service, or has been clearly abandoned but still allows creation of new accounts, or chooses to not delete known spam accounts, even when reported; and we are highly unlikely to ever retract an entry.
In all cases we strongly recommend you use a [Federation Policy](https://about.iftas.org/library/example-federation-policies/ ) to aid you in your decision making.###
