Blacklist
Reject messages from specific users before any filter runs.
Last updated October 1, 2026
Add up to 50 user_id values per gateway.
Messages from blacklisted users are rejected instantly — before any filter runs. Toggle the
blacklist on or off from the gateway edit page.
When to use it
- A single user floods your agent and rate limiting isn't enough.
- You need to cut off a known abuser immediately, without touching filter thresholds.
Because the check runs first, blacklisted traffic never consumes quota and never reaches the filters.
