Hello Everyone.
story is really long so i will write it short
i was playing cod4 deathrun mod.server name is iceops(website:iceops.in)
i was banned for 3 days.i changed cd key and rejoin game.then admin saw me and banned me for 8700 days.then i again changed cd key and again again ban.like 300-400 times i talked with admin but now its to late for talk.admin hates me i apologized to him but he never talk with me.
first they banned me ip for stop me then i used vpn programme and admin was mad but he made autokick script for me.(he said that)
