Questions
Why are some lookups "unavailable"?
Some lists refuse queries that arrive through shared or public resolvers, or did not answer in time. We show them as unavailable, never as clean.
I am listed. What now?
Find the cause first (a compromised account or an open relay is typical), fix it, then request removal from each list.
