AirNope

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

Note

AirNope will temporarily remove Safeguard spam because it is becoming as annoying as crypto spam, and it is recognized as a scam.

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 group's owner or an admin, AirNop just reacts 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

FAQ

Is there a privacy policy?

AirNope is designed to detect spam messages and, in some cases, log them for debugging purposes. While logging these messages, 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 during each release cycle or when the bot is restarted.

We are also considering creating 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 take all necessary measures to protect user information should this initiative be considered.

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

Sure!

On your Telegram

The easiest way is to send the message to @airnope_bot. If the message disappears, it means the bot considered it spam and deleted it; otherwise, it's all good.

On your terminal

Alternatively, you can use Docker and your terminal to test messages locally. Download the Docker image, start the REPL and type your message followed by the key press Enter/Return:

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

Or, if you like Rust and have cargo installed, clone this repo and cargo run -- 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)
