AirNope

A simple, silent bot that keeps Telegram groups free from crypto airdrop spams.

What is AirNope?

What it does

When the user posting the message is not one of the group admins or the group owner:

• deletes the message that is probably airdrop spam
• removes from the group the user who posted it

If the user posting the message is the owner or an admin of the group, AirNop just rects with 👀 instead.

What it does not do

• does not post any message in the group (avoids pollution of the group)
• does not keep any history of messages or users

How to use AirNope?

1. Add @airnope_bot to your group
2. Make @airnope_bot an admin able to delete messages and remove users

FAQ

Is there a privacy policy?

AirNope is designed to detect spam messages, and in some cases, it might log them for debugging purposes. While logging these messages, there is a possibility that personally identifiable information (PII) might be inadvertently captured. We understand the importance of privacy and are committed to ensuring that any PII collected is not processed or persisted. Logs are temporary and are deleted periodically, either during each release cycle or when the bot is restarted.

We are also considering the creation of a database of spam messages to further enhance our spam detection capabilities. However, due to our concern about user privacy and the potential risk of PII exposure, this initiative is not currently part of our roadmap. We will continue to prioritize privacy and will take all necessary measures to protect user information should this initiative be considered in the future.

Can I test it to see what messages AirNope would consider spam?

Sure!

On the web

The easiet way to use the playground.

On your Telegram

The second easiest way is to create a group and add AirNope. Since you would then be the group owner, you will need a second account (friends!) to join the group to see the bot in action.

On your terminal

Alternatively, you can use Docker and your terminal to test messages locally. Download the Docker image and start the REPL:

$ docker pull ghcr.io/cuducos/airnope:main
$ docker run --rm -it ghcr.io/cuducos/airnope:main airnope repl

Can I run my own instance of AirNope?

Absolutely!

1. Create a Telegram bot to get your bot's handle and your Telegram API token
2. Deploy the Docker image ghcr.io/cuducos/airnope:main to a publicly accessible URL having two environment variables:
   1. TELEGRAM_BOT_TOKEN with your bot's token
   2. TELEGRAM_WEBHOOK_URL with your public URL (for example, https://my.bot)
