TrueCaptcha Bot

This telegram bot will help you to protect chat from automated bots. It much more better than t.me/Cyberdyne_Systems_bot, because it check that user can recognize image and choose correct emoji (or guess it with small chance).

Features of this bot:

mutes messages from new users and wait 5 min for solved captcha, than ban user for a day and deletes message
greeting user that correctly solved captcha
you can load new emojis and images in bot without any reloads
if it crashed it remembers correct answers to pending captchas and can check users if image/emoji deleted

You can use this bot in Telegram by this nick or install it on your own bot-account!

Usage

To use this bot you must make him administrator and give restrict users permission

Install your own bot

Firstly, clone this repo localy: git clone https://gitlab.com/woem/truecaptcha_bot.git && cd truecaptcha_bot Then install libraries: pip install -r requirements.txt You can use systemd for managing bot startup with my sample systemd unit file. To use it, you must change 11111111:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA to your bot's token, and /path/to/bot/folder to folder with this bot. Than you should run systemctl daemon-reload && systemctl start truecaptcha_bot && systemctl enable truecaptcha_bot and your bot will run even after server reboots.

Adding more emojis and images

All possible emojis and images stored in /path/to/bot/folder/captcha/.

To add emoji, simple create new folder in directory /path/to/bot/folder/captcha/ with emoji symbol. Example: to add emoji of open book (📖) you must create folder /path/to/bot/folder/captcha/📖/

To add image, choose which emoji corresponds this image and save picture in folder /path/to/bot/folder/captcha/_emoji_. For the convenience of the user, use one image to only one emoji. Example: to add img_1.jpg corresponding emoji of open book (📖) you must put file to /path/to/bot/folder/captcha/📖/img_1.jpg

Security advice

You should add more emojis (and images to them) for gathering higher protection from bots (more possible options cause less guessing chance to bot)
