My in-game nick is 7th Bullet, i'm SG-addicted since few weeks

This post is rather a request for server admins, especially Jeuxlinux.fr where i like to play BR. Since couple of days i have problem with player [JUAN]Fernando... this guy used to shoot me as my teammate (not kill, just shoot in the leg for example). He usually do it at the begging of round in the crowd - so i couldn't notice who is exactly shooting at me... But finally i caught him red-handed and the only thing he could said was that i shot him first (!? don't know, maybe few days ago i did it by accident?) and then left the server immediately... I have really no idea why he chose me or maybe i was not the only one and he just finds some pleasure in shooting and irritating his teammates... I'll be grateful for banning this dude or at least for keeping an eye on him... thanx

Cheers
PS: I know sometimes, especially at the beggining of round it's possible to shoot teammates by accident, but this is not the case in here...
