I recently purchased Proxy Leech.
It's a very different sort of proxy list. It doesn't list web proxies, it list port proxies. This is a different sort of niche for me.
The site was originally coded in vb.net. I had no intention of running a Windows server, so Nathan recoded the site in PHP. I think he did an awesome job.
Does anyone have any sage advice for a newbie entering this niche?
