# Feature Toggles

This toggles features by keyword. When a message matches a blocked keyword—for example **`運勢` (fortune)**—the bot will not respond to that message.

#### Rules

You cannot block `bk`. Each keyword must be at least two characters.

### Command List

Enter `.bk add xxxxx` to add a keyword (one per command).

Enter `.bk show` to list blocked keywords.

Enter `.bk del (number)` or `all` to remove keywords.
