Based on issues: #3, #4, #11.

• current to supporters
• current_sub to opponents
• rating to karma

About half of people like sorting, other have don`t. So each one should decide for himself.

Command example

! C++

Send bot messages to the user in private messages,
because bot messages take up too much space.

Please take a look at the list of actual regular expressions for programming languages.

This should be enabled only if automatic deletion of votes activated.

The top by language is not informative, more often I want to know who is familiar with any technology, such as CUDA or Qt

Example command:

топ Python C++

• 2 "+" or "-" per day per user for users with karma < -20
• 8 "+" or "-" per day per user for users with karma >= -20 and karma < 20
• 16 "+" or "-" per day per user for users with karma >= 20

Possible synonyms:

• Thumbs-up and thumbs-down smiles/stickers.
• Expressions of gratitude ("Thank you", "Спасибо", "Благодарю").
• Expressions of agreement ("Agree", "True", "Yes", "Disagree", "False", "No").
• "++" and "--"

Matching # as +4 rep

How can this be implemented in my opinion:

• with the special bot command
• or bot can monitor rules, which placed on Github gists and if it changed - bot change it in a pinned message

Why would it be better?

• Because accessing the rules in a pinned message, which are represented by text, is much more convenient for chat participants. (it is worth thinking at least about people who have the Internet only for using VK, although this may be a bad example, but still)

Instead of attaching a github link, you can attach a snippet. As for the tops, leave it as it is

Bot should send log of votes to every user who want to receive the log information.
This way the log will be decentralized and therefore will be fair. It will be impossible to fake the log.
There should be commands for enabling log subscription and disabling it.

Forms of the questions that can be found on Wikipedia or other dictionaries:

• Что такое X?
• Что значит X?

First bot should try to find it on Wikipedia, then on Wiktionary, and only if nothing found on both services then bot should use Google.

The answer should be a link to the first found result.

• 64 messages per day in chat if karma < -10 and karma >= -20
• 32 messages per day in chat if karma < -20 and karma >= -40
• 16 messages per day in chat if karma < -40 and karma >= -80
• 8 messages per day in chat if karma < -80 and karma >= -160
• 4 messages per day in chat if karma < -160 and karma >= -320
• 2 messages per day in chat if karma < -320 and karma >= -640
• 1 messages per day in chat if karma < -640 and karma >= -1280
• Read only mode if karma < -1280

Bot will forward all messages from main chat to another chat (that is created only for logging).

+1 for each message without censored words
-1 for each censored word

You can add alphabetical sorting for programming languages when sending a message, for example:
instead of Nim, Java, C, Julia
send: C, Java, Julia, Nim

This should be generalization of #23.
GitHub link is just a single type of link.
Bot should support multiple links.
There should be a whitelist of supported domains to prevent users from addition of damaging links.

• Welcome new user
• Invite to set the languages list
• Invite to set the github link
• Mention the help command

the bot does not delete messages with + as reply on the other message, if 6 hours have not passed since the last one +

Delete all bot messages аfter a certain period,
because bot messages take up too much space
аnd it becomes uncomfortable to scroll through them every time.

I believe that the bot after scoring + or - should give feedback in the chat that everything was successful :)
