How can i detect an elite proxy? it's ok if i don't get them all, since it won't be possible but atleast most of them?

Activities that should require more than one destination (most web browsing) yet constantly show up as the same destination are a good indicator of a proxy.

If a single site accounts for more than 20-30% of a user's request, it might be worth looking into to see if that is a proxy or not. This should mean you'd only ever manually investigate 2 or 3 sites per user. You can adjust this threshold as convenient.

For sure, you need solid logging for your network environment.
