There was a bug in server which caused wrong default spawn pos for all team, all the skins were affected by it. The position you had spawned in the video is not the default spawn position of Free Skin, so he thought it was your spawnloc/diepos which is not against the server's rules to kill you. So, i've to deny this topic as it's just a confusion and script bug.
All reports of spawn-killing at default spawn position that's affected by the bug should be denied. Any players who got banned and affected by the bug can post unban appeals or PM me for an unban.
