So I tried this a while back just to see what the fuss was about with free proxies. Thought I'd save a buck or two. Big mistake. The thing is they're a poison pill for any serious work. The speeds are trash, IPs are recycled and flagged faster than you can say 'ban'. Security? Non-existent. You're basically handing over your data to some random who's probably got a bot farm running on those IPs. It's a trap, and it's not worth the headache. I got caught up in a scrape that I thought was low risk, but man, the damage to reputation and the time wasted trying to clean up the mess was not worth a freebie. Trust me, if you're serious about scraping, ad verification or any anti-detection stuff, don't gamble with free proxies. You're better off investing in a legit provider, even if it costs a little more. The long term ROI on paid proxies is so much higher. I'm sharing this as a warning cause I've been burned, and I see too many new guys still chasing free options and ending up with a dead end. Keep your LTV high and your back end clean. Don't get cheap on your proxies.
