Free and paid proxy servers
Free proxy servers cost nothing and are easy to access. Unfortunately, that's where the advantages end and the disadvantages begin.
Free proxies have many users, so the speed is low, and the signal is unstable. Information passing through such servers is most often unprotected. Most free proxies are regularly blocked.
Paid proxies give the owner reliable and stable access; no one but the owner will use the IP address. They protect data and work at high speeds.
