10 best anti-spam bots for Telegram

Protecting your Telegram group from spam requires reliable automation. Anti-spam bots can automatically detect and remove spam messages, ban malicious accounts, and enforce group rules — saving administrators hours of manual moderation. Here are the 10 best anti-spam bots for Telegram in 2025, ranked by features, reliability, and ease of use.

Why You Need an Anti-Spam Bot

Telegram groups are frequent targets for spam, scam links, crypto fraud, and mass-joining bot attacks. Once a group reaches a few hundred members, manual moderation becomes unsustainable. A dedicated anti-spam bot works 24/7, reacting in milliseconds to threats that human admins would miss.

Key capabilities to look for include:

  • Automatic message filtering (links, forwards, offensive content)
  • CAPTCHA verification for new members
  • Flood control to prevent message bombing
  • Customizable rules that fit your community's needs
  • Analytics and logging for moderation transparency

The 10 Best Anti-Spam Bots

1. Combot (@comaborot)

Combot is one of the most feature-rich moderation platforms for Telegram. It combines anti-spam with deep analytics, making it ideal for large communities (10,000+ members).

  • Spam detection: AI-based filtering with customizable sensitivity
  • CAPTCHA: Multiple verification modes (math, button, custom questions)
  • Analytics: Member activity graphs, message statistics, growth tracking
  • Reputation system: Members earn trust over time, reducing false positives
  • Pricing: Free for groups under 200 members; paid plans start at ~$10/month

Combot is particularly strong for communities that need both moderation and engagement insights in one tool.

2. Group Help Bot (@GroupHelpBot)

A versatile all-in-one admin bot with solid anti-spam features and an intuitive setup wizard.

  • Spam filters: Blocks forwarded messages, links, stickers, and specific media types
  • Welcome messages: Customizable greetings with CAPTCHA challenges

  • Minimal setup: Add the bot, make it admin, and it works immediately
  • Open source: Code is publicly available for audit and self-hosting

Shieldy is the go-to choice if your primary problem is bot accounts mass-joining your group. It won't filter message content, so pair it with another bot for comprehensive protection.

  • Automatic spam detection: Powered by Telegram's own ML models
  • No setup required: Enable in Group Settings → Administrators → Aggressive Anti-Spam
  • Recent senders report: Review auto-deleted messages in the "Recent Actions" log
  • Limitation: Less customizable than third-party bots; no CAPTCHA, no keyword filters
  • Pricing: Free, built into Telegram

Start with Telegram's native anti-spam as your foundation, then layer a third-party bot on top for granular control.

How to Set Up an Anti-Spam Bot

Step 1: Choose Your Bot

Consider your group size, primary spam type, and budget. For most groups under 5,000 members, Rose or Shieldy + Telegram's built-in anti-spam is sufficient.

Step 2: Add the Bot to Your Group

  1. Open your Telegram group
  2. Tap the group name → Add Members
  3. Search for the bot's username (e.g., @MissRose_bot)
  4. Add it to the group

Step 3: Grant Admin Permissions

The bot needs specific admin rights to function:

  1. Go to Group Settings → Administrators
  2. Find the bot and tap Edit
  3. Enable: Delete Messages, Ban Users, Pin Messages (if needed)
  4. Save changes

Step 4: Configure Rules

Most bots respond to commands in the group chat:

  • /antispam on — Enable spam protection
  • /captcha on — Enable join verification
  • /setwelcome — Set a welcome message
  • /blacklist add [word] — Block specific terms

Refer to each bot's documentation for its specific command syntax.

Tips & Best Practices

  • Layer your protection: Use Telegram's built-in anti-spam + one third-party bot. This creates redundancy without conflicts.
  • Start with moderate settings: Overly aggressive filters generate false positives that frustrate legitimate members. Tighten gradually based on actual spam patterns.
  • Enable CAPTCHA for groups over 500 members: Below that threshold, manual moderation may suffice. Above it, automated join verification is essential.
  • Review moderation logs weekly: Check what the bot is catching and adjust filters. You may find legitimate messages being blocked or new spam types slipping through.
  • Keep a human admin active: No bot is perfect. Designate at least one admin who checks the group daily for edge cases.
  • Use web mirrors for SEO: Spam-free groups with quality content can be mirrored to the web via services like tgchannel.space, making your curated discussions discoverable by search engines.

Common Mistakes

Mistake 1: Running multiple anti-spam bots simultaneously
Why it's wrong: Bots can conflict, double-punish users, or create confusing duplicate messages.
How to avoid: Use one primary anti-spam bot plus Telegram's built-in filter. Disable overlapping features.

Mistake 2: Setting CAPTCHA timeout too short
Why it's wrong: Legitimate users in different time zones or with slow connections get kicked before they can verify.
How to avoid: Set timeout to at least 5 minutes. For international communities, 10–15 minutes is safer.

Mistake 3: Never updating filter rules
Why it's wrong: Spammers evolve their tactics. A filter list from six months ago won't catch today's spam patterns.
How to avoid: Review and update your blacklist and filter settings at least once a month.

Mistake 4: Forgetting to grant sufficient permissions
Why it's wrong: A bot without Delete Messages or Ban Users permissions can detect spam but cannot act on it.
How to avoid: After adding any moderation bot, immediately verify it has the required admin rights.

Mistake 5: Ignoring CAS (Combot Anti-Spam) integration
Why it's wrong: CAS maintains a global database of known spammers. Without it, your bot only learns from your group's history.
How to avoid: If your bot supports CAS (Rose, BanHammer, and others do), enable it — it's free and significantly improves detection accuracy.

Frequently Asked Questions

Can anti-spam bots protect Telegram channels, not just groups?
Channels have limited spam exposure since only admins can post. However, if you have a linked discussion group, you should absolutely add an anti-spam bot to that group. The bot cannot moderate the channel itself, only the associated group chat.

Do anti-spam bots read all messages in my group?
Yes, bots with admin access can read all messages. Choose well-known, reputable bots with transparent privacy policies. Open-source bots like Shieldy offer the highest transparency since you can audit the code yourself.

Will an anti-spam bot slow down my group?
No. Telegram bots process messages asynchronously through Telegram's API. Even in groups with thousands of active users, a properly maintained bot introduces no noticeable delay.

Can I use anti-spam bots in private groups?
Yes. All listed bots work in both public and private groups. Simply add the bot as a member and grant it admin rights, regardless of the group's privacy setting.

What should I do if the bot wrongly bans a legitimate member?
Most bots provide an unban command (e.g., /unban @username). Check the bot's moderation log, unban the user, and adjust your filter sensitivity to prevent recurrence. Some bots like Combot offer a reputation system that reduces false positives over time.
