Why am I kicked from servers? Don't have a VPN enabled so why?

Why do I keep getting kicked from certain servers? 

It isn't all servers i am getting kicked from but servers like Banzore or TGB. 

The admin posts that i am kicked for not having VPN disabled but I don't have a VPN. I have gone into settings and have everything turned off. 

I even ran my punkbuster files and i can't find anything wrong. 

Someone help i want to play on all servers.
