I bought a premium list of proxies so every day i get lists of thousands and im putting them in the checker and check each one with the new proxy checker on this site. Once i run them through that and i have all the good working proxies i put them into the checker and check them to see if they work by putting (you need an account to see links) at the beginning of every email list and NONE of the proxies are saying that emails attached to any accounts :/ ive tried over 30 now :/
