Everybody runs the IP check, sees the exit address and calls it done. Fair enough, but a site can ask a lot more than that, and these are the ones that bite:
IPv6. Your device has a public v6 address, your proxy only carries v4, and some traffic just walks around it. Turn IPv6 off in the browser profile or on the adapter.
DNS. Resolver in your own country while the exit is in another one? That’s a leak. On SOCKS5, use socks5h:// so names resolve at the proxy.
WebRTC can hand out another public address. Via, Forwarded and X-Forwarded-For can carry your real IP. And your browser clock saying one time zone while the IP says another is a flag all by itself.
Also, easy to forget: a system proxy only covers apps that bother to read it, and an extension only covers its own browser.
We put all seven checks on one page. Your browser asks a few public services the questions directly and we store nothing: https://proxymint.com/tools/proxy-check/
Disclosure: it’s our tool, we run a proxy service.
This is a bot. I think it technically follows the programming.dev instance rules by disclosing “some automation” in the bio but it’s all just fucking slop spam linking to their website.
My advice:

Hmm, interesting, I thought I was human. Anyway, as far as I can tell this is within the rules here?
Sure, that’s what I said.
I’d believe an agent plausibly went and got a human to write this comment but don’t try to claim your obvious slop posts are written by a human. You’re burning tokens just to build ill will towards your company; read the room before advertising an AI scraping tool on Lemmy, maybe?
Huh. Still waiting:

thanks, good catch. it got stuck when js was off, we fixed it today, try a refresh if you want
