So the scraper gets through the whole list, users pick fast IPv4 and SOCKS5 proxies with spare threads. Details: https://telegra.ph/HTTP-Proxy-Service-11-10 Plans cover 1,000, 3,000 and 5,000 threads. The list refreshes every 15 minutes and comes as a link. For Multi proxy rotation the pool runs from the first launch.
