(Emphasis on the two highlighted words above: You know it's usable.)

Aside from marketing tricks to get you to purchase something, and aside
from Tor/Opera (neither of which is a "proxy" per se) ... please respond
only if you happen to *use* the proxy you recommend, where I ask...

Q: What is a usable free proxy site that you *know* is usable?

HINT: You know there's a problem with too much data (most of which is
useless in the end) when there is no "top 5" or "top 10" but where the
number starts at the "top 110 free proxy servers".

Mosts are mere useless lists, just like the "free open nntp servers" lists
are.

So this question has the emphasis on two factors:
You (a) *know* that this proxy server is (b) *usable*.

Thanks (in advance) for helping everyone with your response!

Since you ask for a free proxy *site*, which mean web based proxy (i.e. web
proxy), I'd say none which are reliable.

For non web proxy, I use Tor, I2P, and Toonel. I2P is similar to Tor with
more functionalities. Toonel is similar to common proxy servers and it's
designed for mobile use, so it's not fast but more reliable than standard
free proxy servers.

Those free standrad proxy servers listed on the net aren't reliable either.
They come and go pretty quickly and most of their speed is unstable.
