proxybot
proxybot is a tiny single-file python script that creates gateway between Telegram groups and users. Users can send messages to certain group and receive messages from that group.
Who needs this
If you got banned (e.g. for spam), you cannot use public chats. Ask chat admin to add the your bot and you can communicate again!
Installation and running
You need Python 3 (tested with Python 3.7.2) and pyTelegramBotAPI library (tested with 3.6.6). Create new bot via Bot Father. [!] Attention - disable privacy mode in the bot settings, that's very important, otherwise your bot won't be able to access group messages. Get your token and paste it to config.json. After that, simple run it with python proxybot.py without any arguments.
Usage
Firstly, you need to retrieve your user ID. Send /getid command to bot. Then open config.json with text editor and add yourself to admin list:
"admins": {
"yournickname": 12345678
},Replace yournickname and 12345678 with any nick (not necessarely your username) and your ID respectively. Restart the bot and you are ready to go! Check out command reference below to get involeved in the bot usage.
Understanding messages transferring logic
There are users and groups. You send message to bot - it forwards your message to group. Lets call it PM -> Group message. When someone in group sends a message - bot forwards it to you, that is Group -> PM message.
The /switchgroup command selects a group for PM -> Group messages for all users. So you choose one certain group to send messages to. But at the same time all the users receives messages from all the groups regardless of any options.
Therefore, PM -> Group messages have only one recipient and Group -> PM have multiple.
Permission system
Users have access to /groups, /switchgroup and /users commands. Admins have access to all the commands, including user commands.
Note that only users get their messages sent to groups and receive messages from groups, it won't work if you only in admins group but not in users.
Command reference
/getid
ID of chat (user id if sent directly to bot or group id if sent in the group)
/groups

/addgroup <group_id>
Add new group
/removegroup <group_index>
Remove the group (pay attention to parameter - it is index that showed by
/groupscommand)
/switchgroup <group_index>
Select group to send messages from users (users receive messages from all groups regardless of this option). Use
/switchgroup noneto reset current group
/users
List of all users
/adduser <user_id>
Add new user (alias doesn't have to be username, any alphanumeric text)
/removeuser

/noforwardprefix
If PM -> Group message starts with this prefix, bot won't forward your message and will send its text only. Allowed characters to use are
!#$&*+<=>-~. To disable this feature simply send/noforwardprefixwithout arguments
