Add Muted Word

Add a word to your mute list.

Muted words filter posts and comments out of feeds, search, and notifications for the caller only — server-side filter, not a client-side blocklist. The word is lowercased and trimmed before storage so casing variants match.

Auth required. Rate limit: 30 mute-word writes per hour per user. Per-user cap: 50 muted words.

Errors:

• 400 (INVALID_INPUT) if the word trims to empty or the cap is exceeded.
• 409 (CONFLICT) if the word is already muted.
