DeFendy: Group Protection Bot

A group grows, and so does the junk: links from strangers, bot accounts posting ads, insults at three in the morning. DeFendy takes that chore off your hands. Add it to the chat, give it admin rights, and it starts cleaning the conversation by itself. 🛡️

It is a moderation and protection bot for Telegram groups. Its profile lists more than a hundred features, and the main ones are easy to grasp.

Spam gone before anyone sees it

The anti-spam filter removes advertising messages and blocks bots that mass-post. A human admin cannot react fast enough, especially in a big group where messages arrive in a constant stream.

Link removal is a separate setting. If you want an ad-free chat, one command cuts outside addresses, so you do not have to scroll through the feed and delete things by hand.

When a crowd storms the chat

Raids look the same every time: a dozen accounts show up within a minute and flood the conversation with identical messages. The anti-raid mode exists for exactly this moment. It reacts to a sudden surge and keeps the chat from turning into a dumping ground.

A captcha for newcomers also helps. A real person taps a button in a second, while a script gets stuck at the door. The /captcha command switches the check on, and many automated accounts drop out without any effort from you.

Troublemakers get muted automatically

Auto-mute silences members who break the rules. You do not have to open the chat urgently because of one rude person. The bot restricts them, and you sort it out later when you have time.

It helps to write short group rules in advance. When members can see what is forbidden, arguing with a mute is harder and your decisions are easier to explain.

Roles and reputation: who deserves trust

The role system gives members different levels of authority. A helper moderator can clean up messages, while an ordinary member can only write. You do not need to make every active person a full admin.

Reputation shows who has been useful to the chat for a long time. Regulars stand out from random visitors, and the community itself hints at whom to trust and whom to reward. 🏆

Small settings that keep a feed tidy

Among the commands there are greeting settings and options to delete join and leave notices. A feed without those lines reads much more easily, particularly in busy groups.

• /help: the list of available commands and setup hints.
• /captcha: a check for new members when they join.
• /deleteLinks: removal of links from messages.
• /greetingMessage: a welcome text for people who just arrived.
• /deleteCommands: cleanup of bot commands so they do not clutter the feed.

Five minutes from install to protection

Setup is simple and needs no programming. A few steps are enough.

1. Add the bot to your group through Telegram search.
2. Make it an admin with rights to delete messages and restrict members.
3. Send /help and see which settings are available.
4. Turn on what you need: captcha, link filter, auto-mute.
5. Watch the first days and adjust the strictness to your audience.

Check these things before you launch

Any moderation bot gets serious power in your group, so look at exactly which permissions it asks for. Grant only what the job needs: deleting messages, restricting members, pinning.

Filters that are too strict sometimes catch ordinary messages. Start with mild settings and tighten them step by step. That way you do not scare off real people and still catch most of the junk. ⚙️

A good habit is to keep at least one living admin in the group who can lift a mute by hand or restore a deleted message. The bot helps, but people keep the final say.
