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](https://t.me/truecaptcha_bot) or install it on your own bot-account!
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](https://gitlab.com/woem/truecaptcha_bot/blob/master/truecaptcha_bot.service). 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.
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`
