Build and Shoot

I started playing this because my brother plays this.I joined a server and it said I was banned.It was Call of liberty arena top 10 maps
my brother stated that he was banned from that server a few minutes ago.I'm guessing that it is an ip ban,So I cannot play on this server.I have done nothing wrong.please help.

your 'brother' also used hacks?

Are you sure it wasn't a Votekick? Votekicks do ban the IP for a preset amount of time.
