Proxy Harvesting

Has anyone else played around with harvesting proxies from their blog spam?

My python script sends me about 15-20/day... this is how I have it setup:

[1] I created a bunch of blogs that are spammer targeted. Everything from electronic reviews, movie blogs, video game blogs, health, etc. I just copied a few articles to get keywords, spun them and let them sit there
[2] I turn off Akismet on wordpress
[3] My python script monitors the mysql database for unapproved comments. When it finds a new one it records the IP address and performs an nmap (port scan) against it. It looks for 80,8080,3128 (actually does a full 1-10000 port scan) etc and tests the IP to see if it is a proxy. The output is to a text file. I don't have a python script to test if its anonymous or google ready but that's about 15more lines of code tops.

TODO:
Implement back end database to store found proxies, test times, country of origin, uptime stats, etc.
Implement SOAP web service for all of my other scripts to request a proxy depending on the task (i.e. Get a google proxie for tasks that need it but stick to Anonymous proxies for simpler tasks. Return a country specific proxy)

Thoughts? Suggestions?

Seems like a great concept especially if you fine tune it. You might want to consider making this a premium plugin for wordpress and selling it here on bhw. I'm sure you could find some customers.

Unfortunately this wouldnt be just another WP addon because of the tech stack it has. It's a great idea to passively gain some free proxies, but as OP said... These proxies suck for tasks. Ok to scrape data though.

That's not a bad idea.And i'm sure this could be expanded to do interesting things.. hm.

Scanning 1-10000 ports might take very long. You can also implement in such a way that they script only scan the ips with the http ports such as 80,8080 and so on...
Just my 2 cents.

This is quite clever! Kudos for the creativity!
