Python Crawler Script for Comments

I need a Python-based tool that can crawl the web, detect open comment sections on blogs, forums, and news sites, and leave short promotional messages automatically. I will supply a pool of ready-made snippets; dropping in a link.

Key behaviour
• Discover pages with comment forms on the three platform types mentioned above and parse the fields needed to publish a reply.
• Select a message at random from my list, decide (also randomly) whether to attach its embedded link version or its plain-text counterpart, then submit.
• Log each action clearly (URL targeted, time, content variant used) so I can track what was posted where.
• Let me tweak basic settings—delay range between posts, maximum daily submissions, list of user agents, proxy details—through a simple config file.

Deliverables
The fully commented .py script, built with common libraries such as requests, BeautifulSoup, or Selenium (your choice).

I will test by running the script against a small list of public pages; a post must appear on each without manual intervention for the work to be accepted.
