Minecraft username: master_blaster12

Description of problem: While I was going through a list of my clan members and I noticed that some of them were either banned of inactive for a very long time when I tried doing /party kick <player> it would not work for the ones who had too many capital letters in their name. I suppose this has something to do with bypassing caps and I was wondering if it could be fixed. I have spoken to kingnick7890 about this too and he says that he cannot kick a player who has all caps in his name.

 

Well it was xXStand_In_AweXx but whenever I put the username in it said "xxstand_in_awexx is not in your party". Afterwards I ended up leaving that party to join a friend's and last night he said he couldn't kick someone with all caps in his name, but now today he was able to kick that player. I don't know if it has something that this player happened to be banned but I'm not sure.
