Alright, so I got burned one too many times with these free proxies. Thought I'd save a few bucks and tried some random free lists but man, it's like playing Russian roulette with your campaigns. They slow down everything, get flagged fast, and worst of all, your data quality tanks. I was trying to scrape some decent data for a client, and these free proxies kept dropping out mid-scrape or worse, redirecting to some spammy site. And don't even get me started on the IP blacklists. It's like trying to fix a leak with duct tape - short term fix but the damage is just waiting to explode. Honestly, I don't get how people still trust these. For me, they're more trouble than they're worth. Switched to private residential proxies, and the difference is night and day. Less downtime, better speed, and most importantly, more consistent leads. So if you're still riding the free proxy train, ask yourself how much are you really saving? It's pennies upfront but costs a lot in conversions and frustration. Just my two cents, but don't say I didn't warn ya.
