Telegram Warn Bot

Telegram Warn Bot made with C# and ♥ by Geras1mleo

What can I do?

I am a bot-moderator...

I keep track of the warnings and automatically ban members when the maximum amount of warnings has been reached.

First of all you have to add me into your chat. To use a default one, search for @fancy_moderator_bot

Promote me to admin and /warn the bad guy by replying to his message or by mentioning @bad_guy in your command. I will ban users who receive more than a certain number of warnings specified in Configuration.json.

The default value of MaxWarnings is 3, which means that the user will be banned on his 3^rd warning.

If the bad guy behaves less badly, you can /unwarn him in the same way. If a member is already banned from chat, I will unban him so he can get back into the group.

All members can check their number of warnings by typing /wcount, or /wcount @bad_guy to check the number of warnings of someone else.

The commands /warn and /unwarn are only available to administrators and the owner of the group.

I can also:
delete "User joined/left chat" - messages...
delete spam (external links / URL's and mentions) of newly joined members (<24 hours in chat, See: NewMemberStatusFromHours)

Triggers

I will look at the messages in one specific chat (or any chat) and respond/trigger to the most offensive/provocative/funny ones.

Illegal Triggers

I will look at the messages in the chat and notify admins (in private messages) if something illegal has been sent in one specific chat (or any chat). I will delete messages with illegal words and optionally also give an auto warning to the sender.

Usage

Modify json configuration files according to your needs:
