You are right, but I will tell you how I chose a convenient and reliable proxy scraper to automatically collect proxies from websites. First of all, it was important for me that it should support several types of proxies, namely HTTP, SSL, etc., and it was also important that it should be reliable, have customizable filters, the ability to rotate proxies, and also have a user-friendly interface. Taking all these aspects into account, I found a proxy scraper that meets my requirements and fulfills my expectations in terms of speed, accuracy and ease of use, here it is https://goless.com/marketplace/proxy-scrapper .
