```
--remove to re-allow, --list to audit)retalk block <name-or-fingerprint> --dir "<user>/identity" # block
retalk block --remove <name-or-fingerprint> --dir "<user>/identity" # re-allow (unblock)
retalk block --list --json --dir "<user>/identity" # list blocked senders
Blocking drops a sender's incoming mail during receive before any
decryption (so they can't consume a one-time key), and tells the relay to
refuse their resends. Local to this identity. If no sender was named, use
AskUserQuestion. Target the identity inline with --dir "<user>/identity".
--remove <name-or-fingerprint> re-allows a sender (a no-op if they aren't blocked).--list --json prints the current block list (one {"fingerprint","name"} per line).(agent-talk receives only from designated peers, so a blocked sender is already excluded from reads; block additionally tells the relay to refuse that sender's resends.)
<user>= this session's user directory — an absolute path resolved at init (e.g.~/.agent-talk/users/alice(global) or<project>/.agent-talk/users/alice(local)). Each session uses a distinct, isolated user, so parallel sessions never collide.
