Dude, free checker proxies are a nightmare. I wasted hours before giving up and just using Bright Data’s free trial. It’s not *technically* free long-term, but their detection is spot-on.
Otherwise, maybe try ProxyNova? Their lists are public, but you’ll need to verify them yourself. Not ideal, but better than nothing.
