Hi,
Is it possible to create a bot that, after detecting its name and appropriate variables, is able to write back? As an automatic dice throwing machine.

Good afternoon!
Unfortunately, there is no smart bot for users to communicate with it.
It is possible to make a bot that automatically sends a personal message welcoming a new users and that's all.
You can search the Internet for resources that offer to create free bots for the forums. Then post the bot code on the forum.
