look, trust me I was a pharmacist so I've seen a lot of hype around proxies and blacklists. honestly most of it's just smoke and mirrors. if speed was all that mattered, everyone would be winning but in reality blacklists are the real gatekeepers. good proxies and smart rotation are necessary but not enough if your IPs get flagged constantly. been there done that. the trick is not just getting decent speeds but making your IPs look legit, avoiding patterns and constantly cycling fresh ones. blacklists aren't just a hassle, they're a test of how sneaky you can be. if you rely only on old reliable proxies, they'll catch you sooner or later. my advice? diversify your IP pool, be quick about rotating, and don't get lazy on the footprint. because fr, speed without stealth is like running with a target on your back. based on what I've seen, if you're serious about winning, focus on stealth first, speed second.
