Blocklist
The blocklist is the free part of Reaction Rules. It removes specific emoji reactions as soon as members add them.
Commands
| Command | Description |
|---|---|
/blocklist add <emoji> | Add an emoji to the blocklist |
/blocklist remove <emoji> | Remove an emoji from the blocklist |
/blocklist list | List all blocked emojis |
How It Works
When a user reacts to a message with a blocked emoji:
- HAF Bot receives the reaction event.
- It checks the emoji against the server blocklist.
- If the emoji is blocked, the bot removes the reaction.
- If a log channel is configured, the bot reports what it removed.
Channel Filtering
You can configure which channels the blocklist applies to:
- All channels — Blocklist enforced everywhere
- Include mode — Only block in specified channels
- Exclude mode — Block everywhere except specified channels
Open Admin Dashboard -> Reaction Rules to:
- Add or remove emojis from the blocklist
- Pick emojis from the server emoji picker
- Set a moderation log channel
- Choose include or exclude channel filtering

Setup check
After saving, use Setup check to evaluate the saved Blocklist channels and permissions with read-only diagnostics. It does not add a reaction or delete a message; confirm enforcement with a harmless blocked reaction from a non-admin account.
