Uma API de moderação para o seu bot do Discord

Exemplo com discord.js

import { Client, GatewayIntentBits } from "discord.js";

const client = new Client({
  intents: [GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages, GatewayIntentBits.MessageContent],
});
// your server's rules, in plain language
const RULES = { "no-spoilers": "No spoilers about movies or series" };

client.on("messageCreate", async (message) => {
  if (message.author.bot || !message.content) return;
  // the last messages of the channel, oldest first
  const previous = await message.channel.messages.fetch({ limit: 5, before: message.id });
  const context = [...previous.values()].reverse().map((m) => m.content).filter(Boolean);

  const res = await fetch("https://api.vigimod.com/moderate", {
    method: "POST",
    headers: { "X-API-Key": process.env.VIGIMOD_KEY, "Content-Type": "application/json" },
    body: JSON.stringify({
      text: message.content.slice(0, 2000),
      context,
      rules: RULES,
      user_id: message.author.id,   // turns on the spam score
      scope: message.guildId,       // spam is counted per server
    }),
  });
  if (!res.ok) return;              // the API did not answer: the message stays
  const result = await res.json();
  if (!result.flagged) return;

  const why = Object.keys(result.flags).filter((k) => result.flags[k]).join(", ");
  await message.delete();
  await message.channel.send(`${message.author}, your message was removed (${why}).`);
});

client.login(process.env.DISCORD_TOKEN);

O bot precisa do intent Message Content, que se ativa no portal de programadores do Discord. Se a API não responder, a mensagem fica: a moderação nunca bloqueia o chat.
