For nice proxies, you have to buy them (they are also sometimes referred to as rotating proxies or UHQ proxies). The proxies we normally use are just virtual and meaningless. We don’t know when they will permanently die or respawn again. For example, I currently have 300 active proxies and 20,000 inactive proxies. Those 20000 might revive and become 20300. It often happens in account cracking.
