It's just what I was looking for. I want to better manage my server in C.S. 1.6, and this software will be a great tool to keep all the hackers and bots away. Most of them use VPNs and proxies to connect and are quite difficult to detect in manual mode.
There's nothing bad in using
a good proxy server from Shift Proxy, but it becomes problematic when cheaters and hackers use the same server to sabotage the game. That's why many admins have to ban the usage of any VPNs and proxies in general. It's because of people who abused these safety measures and used them to their own advantage.
