Why don't you use permalinks, it would be great for seo.
About the proxy lists, I didn't noticed 800 a day after the submission of my proxies. Maybe I should launch my networks sundays and not thursdays ^^
I made another blog post today about proxy listing websites
These are all the best I could find, and normally they should all be active & working, as all bad ones are removed from the list one week ago
You can find them here: Proxy Listing Sites
Though, the best one is ProxLists.Com ofcourse (Next to proxy.org & tech-faq.com )
None of my proxy directories are in the list, i approve sites daily, probably were considered bad.
Every single proxy of mine lists to your proxy list and as long as you keep giving us information like this I'll keep adding you to all my sites
