the only dodgy frag is the 1st in 2nd round, after that all is normal
that 1st frag can be luck, or simply that he saw CTs at the same spot in rounds before
i can not see more suspicious on demo
btw Bee, compress demo´s file with Unzip or Winrar. and change nick for record a demo is a very good idea, coz a lot of players turn on/off if they see some admin on. but BEFORE ban you must change ur nick again, to get recorded in banlist with your real nick
lets see what other admins say
