man, this takes me back. Ten years ago you'd buy a cheap list, pop in some IPs into your bot or scraper, and call it a day. It was all about quantity over quality because the detection wasn't as sharp. I remember running campaigns with lists from sketchy forums and still pulling profit. Fast forward to last week. Tried to scale a localized ad account setup using a 'premium' geo-targeted proxy list. Spent $240 on the list itself. Burned through $1,200 in ad spend over 3 days before realizing the connection success rate was about 60% and the speed was killing my session persistence. The accounts kept getting flagged for 'unusual activity' because half the proxies were already burned or just painfully slow. Switched mid-campaign to a major provider's rotating residential proxy API for another $300 that month. Success rate jumped to 98%, setup time per account dropped from like 10 minutes of manual config to under 2 minutes via their API integration, and those same accounts stopped getting instant verifications. The TL;DR for automation now is simple: if you're doing any volume at all, like more than 20-30 tasks an hour, just use an API. The lists might look cheaper upfront but the time waste and hidden costs when things fail will eat you alive. It's not 2014 anymore.
