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
|
|

|
## Usage
|
|
To use this bot you must make him administrator and give restrict users permission
|
|
|
|
## Install your own bot
|
|
You can use systemd for managing bot startup with my [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.

### 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)
