Thanks for your reply and detailed explanation. Probably you confused something, it is imposible to get 30.000 proxy servers (except if you also cound dead ones). We do proxy check none stop in more than 600 threads in total and we hardly manage to surve users with 15.000-25.000 working proxy servers during a day. The only logical explanation is that you bought a BotNet and running your own proxy servers but 30.000 is too much and requires several dedicated servers to control them.
Anyway we will wish you good luck with your project. If you need any help, you can always contact us at any time
