sooo heres the thing, tried to scale up with some new proxy pools recently. went the DIY route, got a handful of residential providers. big mistake. some of these guys are outright garbage, slow as hell, flaky IPs, and some even keep leaking info or worse. quick lesson - not all proxy providers are equal, even if they look cheap or have a shiny site. you get what you pay for. if youre building your own pool, stick with verified providers, test extensively, and dont trust anyone just because they claim they got the best deal. its all about the quality, not just the numbers. save yourself the headache and cut the bad apples early.
