🚀 Implementation Guide

💻 Discord.js Example

const { Client, GatewayIntentBits } = require('discord.js');
const client = new Client({ 
  intents: [
    GatewayIntentBits.Guilds, 
    GatewayIntentBits.GuildMessages, 
    GatewayIntentBits.MessageContent
  ] 
});

// Regex patterns collection
const autoModPatterns = {
  inviteLinks: /(?:https?:\/\/)?(?:www.|ptb.|canary.)?(?:dsc\.gg|invite\.gg|discord\.link|(?:discord\.(?:gg|io|me|li|id))|disboard\.org|discord(?:app)?\.(?:com|gg)\/(?:invite|servers))\/[a-z0-9-_]+/i,
  emojiSpam: /(?s)(?i)((|\p{Extended_Pictographic}|[\u{1F1E6}-\u{1F1FF}]|[0-9#\*]\u{fe0f}).*){7,}/,
  inlineLinks: /\[.*[a-z0-9_\-]+\.[a-z]{2,}[\/]?.*\]\(<?(?:https?:\/\/)?[a-z0-9_\-\.]*[a-z0-9_\-]+\.[a-z]{2,}.*>?\)/i,
  headings: /^(> )?#{1,3}\s.*$/m,
  subtexts: /(?m)^-#\s.*$/
};

client.on('messageCreate', async message => {
  // Ignore bot messages
  if (message.author.bot) return;
  
  const content = message.content;
  
  // Check each pattern against message content
  for (const [type, pattern] of Object.entries(autoModPatterns)) {
    if (pattern.test(content)) {
      // Delete violating message
      await message.delete().catch(console.error);
      
      // Send warning message (auto-delete after 5 seconds)
      const warningMsg = await message.channel.send(
        `⚠️ ${message.author}, your message was removed for containing prohibited content (${type})`
      );
      
      setTimeout(() => warningMsg.delete().catch(console.error), 5000);
      
      // Log violation to mod channel (optional)
      const modChannel = message.guild.channels.cache.find(ch => ch.name === 'mod-logs');
      if (modChannel) {
        modChannel.send({
          embeds: [{
            title: '🛡️ AutoMod Action',
            description: `**User:** ${message.author.tag}\n**Channel:** ${message.channel.name}\n**Violation:** ${type}\n**Content:** \`\`\`${content.substring(0, 1000)}\`\`\``,
            color: 0xFF5555,
            timestamp: new Date()
          }]
        });
      }
      
      return; // Stop checking after first violation
    }
  }
});

client.login('YOUR_BOT_TOKEN');

📈 Advanced Usage

🔧 Customizing Patterns

You can adjust the emoji spam threshold by changing the {7,} value:

// For 10+ emojis instead of 7+
(?s)(?i)((|\p{Extended_Pictographic}|[\u{1F1E6}-\u{1F1FF}]|[0-9#\*]\u{fe0f}).*){10,}

🌐 Adding Whitelist Exceptions

// Example of whitelist implementation
const whitelistedChannels = ['announcement', 'emoji-channel'];
const whitelistedRoles = ['Moderator', 'Admin', 'Trusted'];

// Add this check before pattern testing
if (
  whitelistedChannels.includes(message.channel.name) || 
  message.member.roles.cache.some(role => whitelistedRoles.includes(role.name))
) {
  return; // Skip automod for whitelisted channels/roles
}
