# Ragnar Bot: Automated Moderation System for Devrant.io

## Overview
Ragnar Bot is an automated system designed to interact with the **Devrant.io API** for community moderation. It detects spam, flags inappropriate content, and takes corrective actions such as downvoting and commenting. The system is scalable, customizable, and supports concurrent operations for multiple users.

## How It Works

### Components
1. **API**:
   Handles all interactions with the Devrant.io platform, including user authentication, content retrieval, and posting actions.
   
2. **Bot**:
   Implements moderation logic:
   - Identifies suspicious content.
   - Posts comments warning users about flagged content.
   - Maintains a history of checked rants to avoid redundant processing.

3. **CLI**:
   Command-line interface to configure and execute the bot. Accepts user credentials and runs bots for multiple users simultaneously.

4. **Victoria Integration**:
   Fetches user-related data from a remote service (`victoria.molodetz.nl`) for enhanced operations.

### Workflow
1. The bot authenticates using the provided username and password.
2. It retrieves and evaluates recent rants for spam indicators.
3. If spam is detected:
   - Posts a predefined warning comment.
   - Downvotes the rant.
4. Maintains logs and runs continuously to monitor new rants.
