Best Anti Spam Discord Bots

Anti-spam bots handle volume problems: message floods, repeated text, mass mentions, emoji walls, unsolicited invite links and the same copypasta across several channels at once. Most combine a per-user rate window with content filters and start punishment at a timeout rather than a ban.

Tune the thresholds against your busiest channel before you trust them, and exempt staff roles and bot channels. Worth checking: whether limits count per channel or server-wide, whether edits count, how muting is implemented (a native timeout or a muted role you have to set up yourself), and how many custom antispam filters the free tier allows.
