Executes the scraper script with various command-line arguments to download media. Supports specifying URLs, output directory, download options (like skipping videos/images), and more. If no URL is provided, the script will prompt the user for input.

```python
usage: scrape.py [-h] [--out OUT] [--sub-folders] [--skip-vids] [--skip-imgs] [--confirm] [--full-hash] [--offset-start START] [--offset-end END]
                 [--dump-urls]
                 url [url ...]

Coomer and Kemono scraper

positional arguments:
  url                   coomer or kemono URL or multiple URLs to scrape media from

options:
  -h, --help            show this help message and exit
  --out, -o OUT         download destination (default: ./out)
  --sub-folders         create subfolders for creators when downloading full pages or posts
  --skip-vids           skip video downloads

### Multithreaded Download with coomer.party-scraper

Source: https://context7.com/a-coom/coomer.party-scraper/llms.txt

This Python code orchestrates multithreaded downloads, featuring automatic retry logic, server rotation (handling 429 errors), and progress tracking. It supports resumable downloads using Range headers, writes to .part files, and verifies hashes to prevent duplicates. The output is organized into timestamp-named files within 'Pics' and 'Vids' subdirectories, with an option for creator sub-folders.

```python
# The CoomerThread class extends DownloadThread with custom logic:
# - Connects to CDN with Range header support for resumable downloads
# - Downloads 2MB chunks with progress tracking
# - Handles 429 (Too Many Requests) by rotating through n1-n4 servers
# - Sleeps when all servers exhausted (THROTTLE_TIME)
# - Computes hash during first chunk to detect duplicates early
# - Writes to .part file, renames on completion
# - Removes .part file on unrecoverable errors (404)

# Directory structure after download:
# ./downloads/
# ╠── Pics/
# │   ╠── 20240315T120000-PostTitle_0.jpg
# │   ╠── 20240315T120000-PostTitle_1.png
# │   ╠── 20240316T093000-AnotherPost_0.gif
# ╠── Vids/
# │   ╠── 20240315T120000-VideoPost_0.mp4
# │   ╠── 20240317T140000-StreamClip_0.webm

# With --sub-folders flag:
# ./downloads/
# ╠── CreatorName_onlyfans/
# │   ╠── Pics/
# │   ╠── Vids/
# ╠── AnotherCreator_patreon/
#     ╠── Pics/
#     ╠── Vids/
```

### Duplicate Detection with Hashing (Python)

Source: https://context7.com/a-coom/coomer.party-scraper/llms.txt

Prevents re-downloading existing files using configurable hash algorithms: quick MD5 (first 64KB) or full SHA256 for bandwidth optimization. Dependencies: Python 3. Input: Creator URL or Post URL. Output: Downloaded media files (skipping duplicates).

```python
# Quick hash mode (default) - hashes first 64KB of files
python3 scrape.py "https://coomer.su/onlyfans/user/examplecreator" \
  --out ./downloads

# Full hash mode - complete SHA256 hash for maximum accuracy
python3 scrape.py "https://coomer.su/onlyfans/user/examplecreator" \
  --full-hash \
  --out ./downloads

# Behavior:
# 1. Scans ./downloads/Pics and ./downloads/Vids
# 2. Computes hashes of existing files
# 3. Quick mode: MD5 of first 64KB of each new download
# 4. Full mode: Prunes download queue based on URL hashes, then SHA256 verification
# 5. Skips downloads if hash matches existing file
```

--------------------------------

### URL Dump Mode (Python)
